Problem
Traversing a single closed loop clockwise, you encounter in this order: (1) the positive terminal then the negative terminal of a 12 V ideal battery, (2) a 150 Ω resistor through which 0.060 A flows clockwise, and (3) an ideal battery whose positive terminal is reached last. Determine the emf of the unknown battery.
