The subsequent problems deal with the circuit shown below. Assume that the diode is ideal (i.e., has a 0V forward bias voltage) and the capacitor has no charge initially. Assume R1 = R2 = R.
Immediately after the power is applied (i.e., the circuit is not in steady state yet), what is the voltage across R1 if Vdc > 0?
A. 0 V
B. 2Vdc
C. Vdc / 2
D. Vdc / 3
E. Vdc
