All batteries in the circuit below have V = 9.0 V. The top resistor has R1 = 20 ?, whereas the bottom resistor has R2 = 10 ?. What is the magnitude of the current I2 that flows through battery V2? For the diagram, make sure you explicitly draw/label all of the loops and junctions that figure into your equation work. For the limits check, investigate what happens to I2 as the resistance on the top segment grows large (R1 ??).
