Question

State the factors on which the resistance of a metallic wire depends .

Answer 1

Answer:

Resistance of a wire is depend upon three factors called

1. Resistivity

2. Length and

3. Area and also in temerature.

But there is also another factor which resistance of the wire also depends that is frequency of the supply. Yes, when we increase the frequency of the supply there would be an increase in the temperature and the increase in temperature increases the resistance of the wire.

So frequency of the supply also plays an important role to determine the resistance of the wire

Answer 2

Answer:

resistance depends on resistivity, length and area
