A battery of electromotive force (e.m.f.) 6.0 V and negligible internal resistance is connected to three resistors each of resistance 6.0 Ω. Which circuit will produce a current through the battery of 0.67 A?

1. ACircuit A: 6.0 V battery connected to one 6.0 Ω resistor in series with a parallel combination of two 6.0 Ω resistors.
2. BCircuit B: 6.0 V battery connected to three 6.0 Ω resistors in series.
3. CCircuit C: 6.0 V battery connected to a parallel combination of two 6.0 Ω resistors in series with a third 6.0 Ω resistor.
4. DCircuit D: 6.0 V battery connected to three 6.0 Ω resistors in parallel.
