2.15 mH coil inductance and internal resistance of 120 ohms connected in series with the capacitor C and the variable external emf peak value is 136 V. The capacitor is selected so that the resonant frequency of the currents in the loop is twice the frequency of the applied voltage 33 kHz. What is the peak value of current in the circuit?
Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
