Question

find the resistance of a wire, when a potential difference of 12V is applied across its ends and 4A of current is flown through it ?

Answer 1

V= IR

R = V/ I

SO ANSWER IS

3 OHM

Answer 2

By ohms law

V = IR

Which implies

R = V/I

I = 4A

V = 12V

By applying formula we get

R = 12/4 = 3 ohm

Resistance = 3ohm
