How does the length of a wire affect the resistance?

Answer 1

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.

Answer 2

As the length of a wire increases, the resistance also increases. This is because there is more material for the electrons to travel through, resulting in more collisions and hindrances to the flow of current, leading to higher resistance. Conversely, as the length decreases, the resistance decreases as well.

Answer 3

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.

Answer 4

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.

Answer 5

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.

Answer 6

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

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