the longer the wire, the more mass the electrons have to travel thru. the more they have to travel thru, the more resistance. (and the resultant heat) the more electrically conductive the wire, the less resistance.

How does length affect resistance of a wire?

In general, the longer the wire the greater the resistance. The only time that this is not so is when the wire is a superconductor, in which case the resistance is always zero.


What are factors that affect resistance of electricity?

Temperature, thickness, length and type of wire.


How does the resistance of a wire vary with its length?

resistance of wire increases with increases of length


What increases resistance in a wire?

Current (measured by an ammeter) and Voltage (measured by a voltmeter) R= V/I Resistance equals voltage divided by current ================================ That's wonderful, but the measurement doesn't "affect" the resistance of the wire. The factors that do "affect" the resistance ... i.e. determine what the resistance will be ... are -- substance of which the wire is composed -- dimensions of the wire: thickness and length.


Three ways which resistance of a wire can be increased?

You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).


How does a wire's cross section affect resistance?

If two pieces of wire are made of the same material and have the same length but different resistance, then the one with the greater cross section area has the lower resistance.


How does the length of a wire affect the resistance?

Yes, resistance is directly proportional to the length, and inversely proportional to the cross sectional area. R = p*l/A. Where R is the resistance of the piece of conducting material, p is Greek letter rho, representing the resistivity of the material, l (lower case L) is the length, and A is the area.


What doesn't affect the resistance of a uniform circular copper wire?

Is either; A. the length of the wire B. the diameter of the wire c. the location of the wire D. the temperature of the wire


How does the thickness of the wire affect resistance?

A thicker wire has less resistance than a thinner wire.


How does the thickness of wire affect the resistance?

A thicker wire has less resistance than a thinner wire.


How does the resistance of a wire vary with its lenght?

If the wire's cross-section area is constant, then its resistance per unit length is constant, and the total resistance should be directly proportional to the length of a wire segment.


What happens to the current of the wire when the length increases?

resistance is directly proportional to wire length and inversely proportional to wire cross-sectional area. In other words, If the wire length is doubled, the resistance is doubled too. If the wire diameter is doubled, the resistance will reduce to 1/4 of the original resistance.
