Define Ohm's law? Give the graph for showing the variation of current with voltage for a conductor.

Text Solution

Verified by Experts

It states that current (I) flowing through a metal conductor is directly proportional to the potential difference (V) applied across the two ends of the conductor provided the physical conditions such as temperature, mechanical strain etc. are kept constant.

That is, `V prop I rArr V = RI rArr (V)/( I) = R`
Where `R` is constant of proportionality and is called resistance of the conductor.
