46. (a) With both switches closed (which effectively removes the resistor from the circuit), the impedance is just equal to the (net) reactance and is equal to X net = (12 V)/(0.447 A) = 26.85 . With switch 1 closed but switch 2 open, we have the same (net) reactance as just discussed, but now the resistor is part of the circuit; using Eq. 31-65 we find net 26.85 100 tan tan15 X R φ = == ° . (b) For the first situation described in the problem (both switches open) we can reverse
