the character "&", representing the word "and"\n\nOrigins: Alteration of "and per se and", meaning literally, "& (the sign) by itself (means) and"\nhttp://www.thefreedictionary.com/dict.asp?Word=ampersand\n\nIn its original form (which differs from the one we currently used) the symbol was a combination of the Latin letters "e" and "t", thus representing the Latin word "et" (meaning "and").   The name "ampersand" itself may have come from the 19th century practice of including this sign at the end when teaching the letters of the alphabet.  For this, to see the earlier form of the sign, and for more on its use see:  http://en.wikipedia.org/wiki/Ampersand\n\n(Example of use: in the 19th century, e.g., in personal letters, you will find many instances of "&c", instead of etc. ("et cetera", meaning "and so forth").

1000 Milli-amps = 1 Amp.  "Milli" is the prefix that means 1/1000 of something, like a Millimeter (1/1000 of a meter), or a Milliliter (1/1000 of a Liter).  It's used frequently in the Metric system, along with the prefixes "Centi" (1/100 of something) and "Deci" (1/10 of something).\n\nCommon rulers that have metric markings will often have Millimeter marks part of the way down.

In  a given material of a given cross-section, the resistance increases with length.  Now conduction is the opposite of resistance, so the shorter it is, the better it will conduct.  \n\nEs mayor en una corta.

yes it means that the system is either in equilibrium or no force is being appplied on the point.(i.e. , no charge is present)

It is the energy possessed by a moving electron through a potential difference of 1 volt.\nThis is the unit of energy in atomic Physics.\n2.247x10^25 ev units are equal to 1 kWh.

Charge is difficult to explain without just saying how it interacts with other charge...\nBasically its a fundamental property of matter, like mass. The difference is, since charge comes in two types, positive and negative, in most large collections of matter, they cancel out and things are generally electrically neutral (have no charge). It responds to other charges through electromagnetism, much like masses affect each other through gravity, and is affected by electromagnetic fields created by currents, and magnetic fields also.\n\nCharge sits on a fundamental particle, or atom, or molecule, or larger particle. If that particle is in a collection of other particles, all of which are moving in the same direction, you have a current - a flow of charge. An ampére (or amp) is a unit meaning "one coloumb per second", or that at a point in a circuit where 1 amp is flowing, one coulomb of (positive) charge is passing per second. The coulomb is actually defined in terms of the ampere - it is the amount of charge that flows past a point in one second when the current is one amp.\n\nIn the example you've given, 240 C passes a point every five minutes, or every 300 seconds. So every second, (240/300) C/sec flows. This is the same as saying that 0.8 (=240/300) amps is "flowing" at that point. The matter is complicated by saying that current flows - it doesn't really, its a property of a stationary point in a circuit. The charge flows. If the rate of charge flow changes, so will the current, but saying that the current flows is a bit of a misnomer. But we're stuck with it.\n\nHope this helps.

Salt (or more specifically, Sodium Chloride salt) is a strong electrolyte, meaning that when dissolved in water it will completely break up into ions (Na+ and Cl- ions).\n\nPure water, by itself, does not conduct electricity, but when you dissolve an electrolyte in it, an electric current can pass through the solution.\n\nIn order for a electric current to flow there must be charge carriers which can move.  Pure water does not have these charge carriers, but after a salt is dissolved and ions are present in solution, the solution becomes conductive.

Amp is a measure of current, which is HOW MUCH electricity flows. There is a relation that can be found between an AMP and how many electrons per unit time.\nVolt is a measure of electric FORCE.\n\nSo, with more FORCE, you can push MORE electrons through a restriction, OHMS.

"Acid Concentration" is well defined.\nIt means: how many acid molecules per unit volume in the liquid.\n   Or more particularly, how many H+ ions are donated by the molecules in \n a unit volume.\nThat because some acid molecules have 2 or 3 H+ ion to donate.\n\nAcid Strength can mean a couple of different things.\n   a) Is that species of molecule strongly acidic?\n         When comparing acid A to acid B, which one donates its H+ ion \n more easily.\n         HCl in water becomes H+ and Cl- right away,\n           so the H+ is just wandering around in that water, looking for \n some damage to do.\n         So we say "HCl is a strong acid".\n         We also say the Acetic Acid in vinegar is a weaker acid.\n          Its molecules H(C2O2H3) try to keep their H's until somebody \n wants it more than they do.\n         The H+ concentration is less, so the acid does less "damage" or \n reacting with things.\n\n  b) Is that solution strongly acidic?\n         A solution is a bucket of water with some concentration of \n chemicals dissolved in it.\n         A strongly acidic solution must have a high instantaneous \n concentration of free H+ ions,\n             regardless of the concentration of other chemicals.\n         A concentrated solution of a weak acid molecule is still a weakly \n acidic solution.\n\nThere are two independent measures of acidity:\n   - concentration of the supposedly acidic molecule,\n             even if it's keeping 99.9% of it's H+'s to itself.\n   - concentration of free H+ ions.\n          The "-log(base10)" of this concentration is called "pH".\n          pH 4  means 10^-4 molar [H+], which is a weak acid solution\n          pH 1 means 0.1 molar [H+], which is a fairly strong acid solution.\nYou need to pin down both to understand the solution well.\n\n\nA pH 4 weak acid solution could be\n     -   a concentrated solution of a weak acid,\n     -   or a 10,000 times diluted solution of a strong acid molecule.\nA strong acid solution with pH=0 can only be\n         a concentrated solution of a strongly acidic molecule.

AC at certain amperage will cause your muscles to contract. making it impossible to let go.

Ampacity: Refers to the how much current a wire can safely carry. For example, a 12 gauge electrical copper wire can safely carry up to 20 amps.\n\nminimum ampacity is not really something that makes sense unless you are talking about the lowest safe maximum and calling that minimum. This might arise from various ways to calculate the safe maximum and then having to use the lowest one. \n\nThe definition above on the link in the sources is not always true for example. If a 12 gauge wire is used in a conduit with a bunch of others and the fill ratio (how much air versus how much wire) of that conduit is greater than the maximum allowed then the current limits on the wires are reduced based upon the amount the conduit is overfilled. Wires in high temperature environments can be a reason to derate them as well.

It means "raise to the power" - (how times you want multiply a number by itself) It has the same function as writing a superscript number afterwards.\n\nE.g., x^2=x*x is x "squared"\nx^3 = x*x*x is x "cubed"\nx^4 = x*x*x*x is x "to the fourth"

I will put it in the order that is easiest to understand.\n\nAmpere: the speed at which electrons pass through\n(1A = 1 coulomb/second, where 1 coulomb is 6.24x10^18 electrons)\n\nWatt: the speed at which work (in joules) is done\n(1W = 1Joule/second. A joule is the amount of work, in Newtons (if you've done physics) x meters,)\n\nVolt:  Watts per Ampere, or Joules per Coulomb\n\nOhm: The RESISTANCE, by Volts per Ampere.

Power is directly related to amperage by the voltage, P=I*V.

Two completely different units.  Amps measure current (flow).  Volts measure voltage.  Voltage= current x resistance.
