Calculate the equivalent resistance of the circuit when a 7.70 V power supply is connected between points A and C.

Calculate the current through R0 and R1

## Homework Equations

Series: resistances sum

Parallel: 1/Req=1/R1+1/R2...

## The Attempt at a Solution

Okay so I'm not really understanding circuits well. From what I would gather R3 and R0 would be in series, but I'm just really confused about R1 and R2. And I'm not even 100% sure if R3 and R0 are actually in series since it branches off to D between them as well..
