Question

Explain ohm, s law. On what factors does the resistance of a conductor depend?

Answer 1

ohm law - potential difference across conductor directly proportional to current passing through circuit.

factor s are

1) area of cross section

2) length

3) nature of material

4) temperature

please follow me

Answer 2

Ohms Law :

Electric current through the conductor is directly propotional to the potential difference applied across the ends and provided temperature and other physical conditions reamians constant.

Resistance of the conductor depends upon

Material

Temperature

Dimension of the conductor
