1. The problem statement(adsbygoogle = window.adsbygoogle || []).push({});

The voltage is on the left (100V) and the jagged lines are the resistors in Ohms. I need to find the equivalent resistance of the circuit and after that the current flowing through the 4 ohm resistor.

2. Relevant equations

I = V/R

3. The attempt at a solution

I'm not sure if I calculated these correctly...

Equiv Resistance = 7 + (10/2) + 8 + (4/2) + 3 = 25 Ohms.

For the current flowing through the 8 ohm resistor, I = V/R = 100V/25ohms = 4 Amps
