Question

what do we understand by ohms law

Answer 1

Ohm's Law deals with the relationship between voltage and current in an ideal conductor. This relationship states that: The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R.
I hope it's helps u alot plZ marks as brilliant answer.

Answer 2

Current flowing through a conductor is directly proportional to the potential difference applied across it keeping the temperature constant.
Acc to dis law
V=IR ☺☺
