Question

8. Please refer to the circuit diagram on the right and find
the following:
a) Effective resistance of the circuit.
b) Current passing through the 3 ohm resistor.
c) Potential difference across 4 ohm resistor.
d) Power rating of the circuit.​

Answer 1

Explanation:

a)

12 ohm and 4 ohm are in parllel

Reff=12.4/12+4

=9ohm

9ohm and 3 ohm are in series

Reff=9+3=12ohm

b)

V=IR

12=12.I

I=1A

it passes through 3 ohm resistor

c)

the parllel combination and 3 ohm are in series so same current pages through it

check attachment for remaining

i=3/4
