Which has greater resistance...?

If the bundle diameter is the same and the individual wires are round in cross-section, then obviously the area of wire metal in the cross section is less in the bundle than in the solid wire so the bundle has a higher resistance. But let's say you mean that the bundle is enough larger in diameter that the metal areas of both cross sections are equal as assumed by answer 2. Suppose there are N strands in the bundle and the solid wire has a resistance R. Then each strand's resistance is N*R. Contrary to answer 2 (if I am reading it correctly), it makes no difference if the individual wires are connected side-by-side or not, as long as they are connected together at each end. Connecting them thus in parallel makes the bundle's resistance equal to R. Since the strands are identical in resistance and therefore carry the same current, the voltage at any distance along one strand is exactly the same as at the same distance along any other strand. Connect them together at that point and what happens? No change in current flow because no change in voltage, and therefore no change in resistance.

Different chemical composition, one has a reaction the other doesn't..☺

Each one kind of answers itself. Resistance is just a different form of working out. You do manuevers that are resistance to normal body movement. Strength training is when you do high weight with low reps (increases strength). Weight trainging is just when you use weights.

Resistance is the physical property of an element that impedes the flow of current.  Here are the basics for a wire:\n\nResistance, R, of a wire is influenced by three main things: (1) the resistivity, p, of the wire, (2) the length, L, of the wire, and (3) the cross-section area, A, of the wire.  The relationship looks like this...\n\nR = (p*L)/A\n\nIncrease the resistivity or length and you increase the resistance.  Increase the cross-sectional area and you decrease the resistance.  Those are the basics anyway.  Hope this helps.

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.

Its is the amount of resistance.  Same reason the wire in a lightbulb grows.  There is some level of electrical resistance, even in conductive materials.  The resistance creates heat and eventual combustion.

They are both resistive elements.\nA resistor is a passive component and a transistor is active\n\nA resistor has a fixed resistance that does not depend on signal polarity or amplitude.  It just sits there and does it's job, so it's called passive.\n\nA transistor resistance varies depending on an applied control signal.  It has a third pin dedicated to the control signal input, where a resistor only has 2 pins.  The control pin is what makes transistors active.\n\nThere are other differences of course, in size, polarity, form factor, material, etc.  I limited my answer to the main point of passive versus active.

Resistance in a wire is caused by ions in the wire getting in the way of electrons. This causes their drift velocity( the average velocity of an electron) to decrease so current (charge per second)decreases because fewer electrons go past a certain point per second. Things can affect resistance, such as \n-heat as if the wire is hot the ions vibrate more and so get in th way of electrons more, \n-thickness of the wire as when it is thicker there are more spaces for electrons to get through, \n-material of the wire as some is more conductive than others,\nlength of the wire as the longer the wire, the more times the free electrons will collide with other free electrons, and the ions making up the metal. Therefore, more energy is going to be lost in these collisions (as heat). \n try this site http://www.bbc.co.uk/schools/gcsebitesize/physics/electricity_and_magnetism/resistance_and_resistorsrev1.shtml

Everyone here, including the asker, is wrong.\n\nThe long rope will carry a greater load than the short one if the initial tension in each is the same.\n\nReason:  The long rope will DEFLECT more than the short, and the angle it makes with the horizontal will therefore be greater.  The greater the angle, the more upward load the rope will carry.\n\nTorque has NOTHING to do with this problem.  The nature of a rope is that is can ONLY support TENSION.  No bending (torque) allowed.\n\nI'll supply the equations in a while; I started scribbling them down, but they got a little hairy, and I wanted more time to sort them out so they're readable.  I like this problem; it's just that you assumed a particular answer was right a priori..........

Well, not everything obeys Ohm's Law (for example, diodes), so it's not really a law.  It is more of a definition of R (resistance) in the sense that IF a system obeys E = I/R then that system has a well-defined resistance, R.

Both will work.The concentrated will work much faster.!00% being strongest and 0 being weakest.

Watts are directly in realtion to Ohms, hence a 120 watt bulb should have more Ohm resistance. The resistance in the fillimant is what creates the heat and light of the bulb, by friction of electrons or something along those lines.

Resistance is the property in an electrical circuit.\n\nAny wire will have some resistance to flow of charges.\n\nThe property that gives hindrance to flow of charges is called resistance.\n\nIf there is any obstacle to the flow of charges then the one which gives this obstacle is said to possess some resistance.\n\nThe resistance is related by this simple equation E = I R.\n\nOr R = E/I. \n\nE is the potential difference and I is the rate of flow of charges.\n\nThe resistance is zero only when I is infinity.\n\nThe resistance is less when I is great for small values of E.\n\nThe resistance is large when I is small for a value of E.\n\nThe potential difference between the ends of a battery is full to its maximum when it is not connected to any external circuit.\n\nThat is when the current is zero the potential difference across the battery is maximum. This maximum potential difference is called E.M.F of the battery\n\nConsider a battery of 2 Volt.\n\nWhen this is connected to a resistor of 2 Ohm the current we expect is 2/2 = 1 ampere. \n\nBut in practice this will not happen.\n\nThe current will be less than 1A. Suppose that the current is 0. 95 A.\n\nAt the same time if we measure the potential difference it will NOT be 2 volt but it will be only 1.9 volt. \n\nThus there is a loss of 0.1 volt.\n\nThe chemicals inside the battery produce this 0.1 volt opposing the 2 volt ( when there is no flow of charges inside the battery).\n\n\n \n\nReturning to the current consideration, we used a battery of 2 volt E.MF and a resistor of resistance 2 ohm. But the current is 0.95 A instead of 1 A.\n\nIf the total resistance were 2.105 ohm instead of 2 ohm , then the current in the circuit will be 2 / 2.105 = 0.95 A.\n\nThus we see that the battery is having some INTERNAL resistance of 0.105 ohm.\n\nThis resistance is due to the production of opposite emf of 0.1 volt to the actual emf of 2 volt (2- 01 = 1.9 V). The potential difference across the battery has reduced to 1.9V from 2 V.\n\nThus the resistance is only a property and there not be any resistor inside the battery.\n\nThis internal resistance is not a constant one and will vary according to the external resistances used in the circuit and other factors.

There is increased resistance associated with the left ventricle due to the larger volume of blood and capillary beds in the whole body vs. just the lungs for the right ventricle.
