Question

if a P.D. of 12v is applied across a 3ohm resister then the current passing through it is ________
a)36 A
b)4 A
c)0.25 A
d)15 A​

Answer 1

Answer:

36 a

Explanation:

3*12=36

p=voltage into ohm

Answer 2

Answer:

We know. from ohm's law

V = I * R

Given V = 12 V

and R = 3 ohm's

Substituting the above values in the ohm's law equation we get I = V / R = 12 / 3 = 4A

Answer is b
