Question

state three factors on which the restince of a wire depends ​

Answer 1

The length of the wire, resistance is directly proportional to the length of the wire. (ii) The cross-section of the wire, resistance is inversely proportional to the cross-section of the wire. (iii) The temperature of the wire, the resistance of wire is directly proportional to the temperature of the wire.
