State and explain ohm's law

Explanation

Ohm.s law: When all the physical conditions surrounding the conductor remain unaltered, the electric current in a conductor is directly proportional to the potential difference between its ends.
If .I. is the current, . V., the p.d. between the ends of the conductor then
`IpropV`
i.e., I= KV where .K. is known as electrical conductance.
V=IR
where, `R=1/K` is knowri as the electrical resistance of the conductor.
