Question

Out of two wires X and Y of same material, wire Y is twice the length of wire

X. which one has greater resistance? Justify your answer.


pls answer fast friends...

Answer 1

Answer:

Resistance of wire Y is Greater

Explanation:

The resistance behaves like an opposing force. It opposes the current flowing in the electric circuit.

The resistance of a wire is given by :

$R = \: ρ \frac{l}{A}$

Its depends on the length and the area of cross section of the wire.

The length of wire Y is double of wire X.

So, the resistance of wire Y is more as compared to wire X. If the area of the both wire are same then the resistances of wire Y is more.
