In the circuit at right, switch S is closed, and is held that way for a very long time. The central branch of the circuit, having resistance R, has negligible self-inductance, but the branch of the right, having resistance 2R, has a non-negligible self-inductance L. If the switch is suddenly opened, what will be the voltage across the inductor at that instant? Express your answer as a fraction or multiple of ℰ, and make sure to explain which side of the inductor (top or bottom) is at higher poential.
