Question

define the term ohms laws? write the mathematical formula and also plot the graph for potential difference verses current? ​

Answer 1

Ohm's Law

According to Ohm's law, the potential difference between two electrodes (V) is directly proportional to the passing current (I).

$v \: \alpha \: i \\ v = \ ri$

where r = resistance.

Hope this helps you...

Answer 2

Answer:

Ohms law states that the V/I is a constant, where V is a voltage applied across a piece of material (such as wire ) and I is the current through the material.

v/i =R or V =IR (where R is a constant).

R is the resistance of the material . The s.I unit of resistance is ohm .
