Question

Define ohm's law? Prove it on the basis of V.I. graph. Also define ohmic and non ohmic resistance?

Answer 1

According to Ohm's law:
At a constant temperature and pressure potential difference is directly proportional to current and potential difference is inversely proportional to resistance.

Ohmic resistance are those resistance which are constant at a temperature and non ohmic resistance are those resistance which are not constant at the temperature.

OHM'S LAW....

It states that at a constant temperature, current "I" through a conductor between two points is directly proportional to the potential difference "p.d" or voltage "v", across the two points. That is, Thus, the ratio V : I is a constant. This constant is called as the resistance "R" of the conductor...

OHMIC RESISTANCE...
Those resistance which are constant at a temperature...

NON OHMIC RESISTANCE....
Those resistance which are not constant at a temperature....
