Expression for current drawn by external resistance using ohm's law
Answers

V = IR
Ohm's law, States that at constant temperature the current drawn by a material is directly proportional to the potential difference.
So, I (proportional to) V
I = V/R
so, V = IR.
where V is the potential difference
I is the current flowing.
and, R is the constant of proportionality, Resistance.
Thankyou!!!
