5054Electromotive force and potential difference
The battery in a circuit contains two identical cells connected in parallel. [circuit diagram: two 2.0 V cells in parallel, currents I1 and I2 labelled, resistor at bottom] Which row shows the relationship between currents I1 and I2 and gives the electromotive force (e.m.f.) of the battery?
- AI1 > I2, 2.0
- BI1 > I2, 4.0
- CI1 = I2, 2.0
- DI1 = I2, 4.0
