Read the series & parallel combinations class notes.
For the circuit shown,
- R1 = 470 Ω
- R2 = 470 Ω
- R3 = 390 Ω
- VS = 23 V
- IS1 = 55 mA
- IS2 = -40 mA

Use series and parallel combinations to reduce the circuit to its simplest arrangement of sources and resistors. Sketch the simplified circuit and give the values for the source(s) and resistor(s).
