- Homework Statement
- Consider the circuit shown in the figure. Calculate the potential difference across 3 Ohm resistor

- Relevant Equations
- I believe V=IR and, R = R1+R2+ R3, 1/R = 1/R1 + 1/R2 + 1/R3... are relevant.

So far, here's what I have:

Taking the parallel-connected resistors alone, 1/Total effective resistance (R) = 1/3ohm + 1/6ohm = 1/2, so R = 2ohm

Replacing the 3 and 6 ohm resistors with a 2 ohm resistor, the total resistance will be 2+4 = 6ohm

Using V=IR,

I (current) = V(potential difference)/R(resistance)

=12V/6ohm = 2A

I've found the total current, but now I'm pretty much stuck???
