Electricity is  flow of electrons in a conductive material like copper or any metals.  The atoms in the conductor are passing the electrons to the next atom in sequence (current flow in Ampere unit). \n\nAnalogy: \nYou can imagine people in line, passing balls in sequence to the next person until the balls reached the other end.\n\nThe force behind the movement of electrons (potential difference in Volt unit), is due to the excessive supply of electron (negative) from one end and lack of supply (Positive) from the other end. (They flow downstream like water).\n\nImagine if you connect two ends of wire to the positive and negative side of the battery. (But don't do it. That is called; short circuit)\n\nIf the wire is cut in the middle and you connect a light bulb between the two cut ends, The light bulb will glow. \n\nHere is the reason;\n\nBecause the light bulb filament (also a metal but doesn't melt easily) is smaller than the wire conductor and does not easily allow the passage of electron (resistance in Ohm unit), The flow of electron will be restricted to a certain amount (like a bottleneck in a pipe) this restriction will cause heat and light due to friction.\n\nMy best tailored answer for you ;=)

the electrical circuit?

By reading many of the answers of this particular question I come to realize this is the blind leading the blind. I am afraid someone is going to get killed. Forget about the fact that you cannot measure current by simply taking ammeter probes and measuring across. If you do not already know this then you have no business in this world attempting to directly measure electricity. And the people supplying this erroneous information are well on the road to becoming toast…………

Your question is not clear at all, but let me guess a little.\n\nAre you asking for the function of each component in the circuit ???\n\nIf so, light bulb will be the load.\nConductor is the mean for the current to flow.\nswitch, is for closing or opening the circuit\ninsulation, to keep conductors to short the circuit.\nmeter, to measure the voltage or current or power being used at some time.\nbattery is the power source to get the circuit to work.\n\nNow I guess I earn 10 points for best and only answer.

Electricity doesn't exactly do work.  Electricity is a form of energy that enables other things to do work.  Like food in your body.  Your body does the work, the food provides the energy.  Electricity is one form of stored energy that is extracted from a number of different sources, like coal, oil, the sun, flowing water, or splitting atoms.

There is a relationship between power P, voltage V and current I. This relationship is best summarised by this formula: \n\nP=IV.\n\nCurrent is something else entirely. It is the rate at which electrical charge flows. The standard unit for charge is the Coulomb, and the standard unit for current is the Ampere.\n\nVoltage is the “push” that excites the electrons in a conductor and makes them flow (as current). Voltage is measured in volts and can be thought of as the potential for charge to do work. \n\npower, electric, energy dissipated in an electrical or electronic circuit or device per unit of time. The electrical energy supplied by a current to an appliance enables it to do work or provide some other form of energy such as light or heat. Electric power is usually measured in Watts

to understand electricity work you need about how bits & byte works.\n\nIf you have used a computer for more than five minutes, then you have heard the words bits and bytes. Both RAM and hard disk capacities are measured in bytes, as are file sizes when you examine them in a file viewer. \nYou might hear an advertisement that says, "This computer has a 32-bit Pentium processor with 64 megabytes of RAM and 2.1 gigabytes of hard disk space." And many HowStuffWorks articles talk about bytes (for example, How CDs Work). In this article, we will discuss bits and bytes so that you have a complete understanding. \n\nDecimal Numbers\nThe easiest way to understand bits is to compare them to something you know: digits. A digit is a single place that can hold numerical values between 0 and 9. Digits are normally combined together in groups to create larger numbers. For example, 6,357 has four digits. It is understood that in the number 6,357, the 7 is filling the "1s place," while the 5 is filling the 10s place, the 3 is filling the 100s place and the 6 is filling the 1,000s place. So you could express things this way if you wanted to be explicit: \n\n(6 * 1000) + (3 * 100) + (5 * 10) + (7 * 1) = 6000 + 300 + 50 + 7 = 6357 \nAnother way to express it would be to use powers of 10. Assuming that we are going to represent the concept of "raised to the power of" with the "^" symbol (so "10 squared" is written as "10^2"), another way to express it is like this: \n\n\n(6 * 10^3) + (3 * 10^2) + (5 * 10^1) + (7 * 10^0) = 6000 + 300 + 50 + 7 = 6357 \nWhat you can see from this expression is that each digit is a placeholder for the next higher power of 10, starting in the first digit with 10 raised to the power of zero. \n\nThat should all feel pretty comfortable -- we work with decimal digits every day. The neat thing about number systems is that there is nothing that forces you to have 10 different values in a digit. Our base-10 number system likely grew up because we have 10 fingers, but if we happened to evolve to have eight fingers instead, we would probably have a base-8 number system. You can have base-anything number systems. In fact, there are lots of good reasons to use different bases in different situations. \n\n\nBits\nComputers happen to operate using the base-2 number system, also known as the binary number system (just like the base-10 number system is known as the decimal number system). The reason computers use the base-2 system is because it makes it a lot easier to implement them with current electronic technology. You could wire up and build computers that operate in base-10, but they would be fiendishly expensive right now. On the other hand, base-2 computers are relatively cheap. \nSo computers use binary numbers, and therefore use binary digits in place of decimal digits. The word bit is a shortening of the words "Binary digIT." Whereas decimal digits have 10 possible values ranging from 0 to 9, bits have only two possible values: 0 and 1. Therefore, a binary number is composed of only 0s and 1s, like this: 1011. How do you figure out what the value of the binary number 1011 is? You do it in the same way we did it above for 6357, but you use a base of 2 instead of a base of 10. So: \n\n\n(1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (1 * 2^0) = 8 + 0 + 2 + 1 = 11 \nYou can see that in binary numbers, each bit holds the value of increasing powers of 2. That makes counting in binary pretty easy. Starting at zero and going through 20, counting in decimal and binary looks like this: \n\n 0 =     0\n 1 =     1\n 2 =    10\n 3 =    11\n 4 =   100\n 5 =   101\n 6 =   110\n 7 =   111\n 8 =  1000\n 9 =  1001\n10 =  1010\n11 =  1011\n12 =  1100\n13 =  1101\n14 =  1110\n15 =  1111\n16 = 10000\n17 = 10001\n18 = 10010\n19 = 10011\n20 = 10100\n\nWhen you look at this sequence, 0 and 1 are the same for decimal and binary number systems. At the number 2, you see carrying first tak

Electricity. It's everywhere. It's in your house, in the computer on which you are reading this, in the air, in your body, blah blah blah. You get the point. It also plays an important integral part of sound systems. From the microphone to the loudspeaker, everything is electrical, and you need to know a few things about it.\n\n\nANYONE FOR FROGS' LEGS?\n\nAn Italian scientist named Alessandro Volta did experiments with electric charge back in the 1800s; he managed to make dead frogs (yes, frogs) "move" by using them as part of an electrical circuit, and is credited with providing us with a lot of information about electric potential. The volt was thus born. Voltage is defined as the electric charge between two points. In household terms, voltage is akin to water pressure available to do work. It can't do any work until a circuit (the plumbing and a water tap) is complete so that current (the amount of water) can flow. In engineering terms, voltage is the potential energy of a bunch of electrons. Current, measured in Amperes, is the flow of electric charge; we can say that current is the rate of flow of electrons, but technically it is the opposite flow that we call current-- as electrons move in one direction, holes are left behind, and appear to flow in the opposite direction. We should also remember from our physics classes that there is a fundamental equation used in electricity: Ohm's Law.\n\n\nOHM SWEET OHM\n\nOhm's Law is the mathematical relationship between voltage, current and resistance. It is named after George Ohm, its founder. Ohm's Law states that the current in a conductor is directly proportional to the voltage across it, and inversely proprtional to its resistance. In simpler terms, the law states that more voltage will produce more current if resistance stays the same, but higher resistance will cause the current to decrease if the voltage stays the same. In our household plumbing example, we can say that Ohm's Law dictates that more water pressure will produce more output if the diameter of the pipe stays the same, but a smaller-diameter pipe will cause the output to decrease if the water pressure stays the same.\n\nWith these three basic components, we have electricity. Current is "drawn" from a power supply due to the presence of a voltage placed across a load, or resistance. For instance, a typical electrical outlet has 120 volt potential (pressure- it has the capacity to give you 120 volts), but nothing is connected. If you put some load across its terminals, like a lightbulb or steam iron, you then have a complete circuit in which electrical current can flow. As we said before, a higher resistance will yield less current than low resistance. A direct short will cause a very large flow of current, because there is no resistance. If the supply is capable of delivering enough current, it is likely that the wire will eventually heat up and melt. This is why circuit-breakers and fuses are used. They limit current flow by opening (as opposed to shorting) a circuit before current flow becomes too large-- a 15A circuit-breaker will trip when the loads connected to that circuit try to pull more than 15A of current.\n\nMakes sense, right? Good. Ohm's Law is represented as the rate of flow of electrons, and voltage is represented as the electric charge between two points.\n\nOhm's Law:V = I x R, where V = Voltage, I = Current, and R = Resistance. \n\nHELL'S BELLS\n\nElectricity appears in two forms: alternating current (AC) and direct current (DC). Direct current does not change directions-- the electron flow is always from the negative pole to the positive pole-- although as we mentioned before, the electrons themselves don't really "move," it's the holes that are created that "move." Direct current is almost always what is used inside of electronic devices to power the various internal components, but it is a harmful thi
