Question

if the pd across 3 ohm resistor is 12 v find the power of each of the resistor connected in parallel​

Answer 1

Explanation:

current through 3 ohm is

V = I R

12 = I x 3

I = 4 A

current through each 4 ohm resistor are in parallel is 2A each.

power dissipated across each 4 ohm is

I²x R = 2² x 4 = 16 W.
