Question

the resistance is 4 ohms and the current following is 3 ampere then voltage is​

Answer 1

as we know that
$v = ir$
i = 3A
r= 4 ohm
hence
v =(3)×(4)
voltage is 12 volts

Answer 2

Hi friend... Thanks for asking this question

Given:- resistance is equals to 4 ohm and current flowing is equals to 3 ampere therefore the voltage is equals to

V = I × R (Ohm's law)

》 V = 3 × 4 = 12 v
