97. Reading carefully, we note that the driving frequency of the source is permanently set at the resonance frequency of the initial circuit (with switches open); it is set at ω d = 1/ LC = 1.58 × 10 4 rad/s and does not correspond to the resonance frequency once the switches are closed. In our table, below, C eq is in µ F, f is in kHz, and R eq and Z are in . Steady state conditions are assumed in calculating the current amplitude (which is in amperes); this I is the current through the source (or through the inductor), as opposed to
