Question

what is the current if 12 ohm and 4 ohm resistor connected in parallel and 12 v potential difference is applied​

Answer 1

Answer:

I=V/R

V=12V

R=R1×R2÷R1+R2

=12×4÷12+4=3

I=V÷R=12÷3=4

Answer 2

Answer:

3 A

Explanation:

1/R = (1/12 + 1/4) ohm = 1/4 ohm

Therefore R = 4 ohm

V = 12 V

We know ,

V=IR

So, I=V/R = 12/4 = 3 A
