Explain about ohm's law?

Answers (1)

Ohm’s law-

In a conductor, if all external physical conditions like temperature and pressure are kept constant the Current flowing through a conductor is directly proportional to the Potential difference across two ends.

I.e  V\propto I

or we can write V=IR

where R- Electric Resistance

From V=IR we can draw the graph  between V and I which is given below

The slope of the graph gives the resistance.
