Question: A series R-L-C circuit is connected to a 0.2V supply, and the current is at its maximum value of 4 mA when the supply frequency is adjusted to 3 kHz. The Q-factor of the circuit under these conditions is 100. Determine the value of the circuit resistance, the circuit inductance, the circuit capacitance, and the voltage across the capacitor.
