Question

Define ohms law and also derive the expression for ohms law

Answer 1

Answer:

Ohm's law states The current flowing through a conductor is directly proportional to the potential difference V across its ends, provided the temperature and physical conditions of the conductor remain the same'.

If lis the current flowing through a conductor and V is the potential difference (or voltage) across its ends, the according

to Ohm's law:

|x V

V

= constant =R

V=IR

R

'R' is constant for a given metallic wire at a given temperature, and this constant is named resistance. It is the property of a

conductor to resist the flow of charges through it.

Its Sl unit is ohm which is denoted as n.
