The coil inductance of 2.15 mH and internal resistance of 120 ohms is connected in series with the capacitor C, and the external variable emf, peak value is 136 V. What should be the capacitance of the capacitor to the resonant frequency of the current in the circuit of 33 kHz? What is the maximum current at resonance?
