Question

In Ohm’s law experiment, the physical quantity/quantities which is/are to kept
constant while doing experiment is/are :
(a) potential difference (b) current
(c) temperature (d) potential difference, current, temperature

Answer 1

Ohm's law state that current is proportional to voltage

I.e. current increases as voltage increases

The proportionality constant for equality is resistance

This resistance is constant

It doesn't depend on current or voltage rather it depends on material of conductor it's length and cross section

Answer 2

Answer:

temperature

Explanation:

if if temperature remains constant thencurrent through the resistor is directly proportional to the potential difference applied across it that is ohm's law . Hence temperature is the physical quantity which is to be kept constant while doing experiment
