Question

state and express ohm's law

Answer 1

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. Ohm's Law is given by: V = I R where V is the potential difference between two points which include a resistance R.

Answer 2

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
