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.

The length of a wire affect resistance because if a long wire is used in an electrical connection.the resistance to be used in driving current round the circuit will be used in overcoming resistance of the lenghty wire.

the length of wire is proportional to the resistance of the wire. The longer the wire the more resistance the wire will have. Current is inversely proportional to resistance. If the resistance goes up, the current goes down. The longer the wire, the less current will flow through the wire.

wire resistance is measured by ohms (unit of resistance) per length. A longer wire, with a longer path for electricity to pass through, has a greater resistance to electricity.

the longer the length, the higher the resistance:

there are more atoms in the wire (or any conductor) for the electrons carrying the energy to bump into. each bump causes energy to be lost (as heat from friction). so the more bumps, the less energy

Yes. We don't ordinarily notice it, because the resistance of wire is so low to begin with. But there's no escaping the fact that a 2-inch wire has double the resistance of a 1-inch wire, and a 1-foot wire has 12 times as much.

longer the wire is the lower the current gets.if you increase the length of wire, the current decreases

The resistance of a wire is directly proportional to its length. If length of the wire is increased, it increases the resistance.

Resistance is directly related to the length of a wire. Greater the length more the resistance and hence more heat loss.

yes, generally the longer the length the greater the resistance or else we could transmit electrical power over immense distances without losses.

the resistance of wire depends upon its lengths of cross section and the nature of the material of the wire.

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?

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.


Why does the length of wire affect the resistance?

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.


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 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.


How does the thickness of the wire affect resistance?

A thicker wire has less resistance than a thinner wire.
