In an oscillating LC circuit, the maximum charge on the capacitor is qm q m. Determine the charge on the capacitor and the current through the inductor when energy is shared equally between the electric and magnetic fields. Express your answer in terms of qm q m, L, and C.
If the capacitor contains a charge before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor (Figure 11.5.1 (a)). This energy is When the switch is closed, the capacitor begins to discharge, producing a current in the circuit.
In an oscillating LC circuit, the maximum charge on the capacitor is 2.0 × 10−6 C 2.0 × 10 − 6 C and the maximum current through the inductor is 8.0 mA. (a) What is the period of the oscillations? (b) How much time elapses between an instant when the capacitor is uncharged and the next instant when it is fully charged?
When fully charged, the capacitor once again transfers its energy to the inductor until it is again completely discharged, as shown in Figure 11.5.1 (d). Then, in the last part of this cyclic process, energy flows back to the capacitor, and the initial state of the circuit is restored. We have followed the circuit through one complete cycle.
The electric field of the capacitor increases while the magnetic field of the inductor diminishes, and the overall effect is a transfer of energy from the inductor back to the capacitor. From the law of energy conservation, the maximum charge that the capacitor re-acquires is q0 q 0.
This continued current causes the capacitor to charge with opposite polarity. The electric field of the capacitor increases while the magnetic field of the inductor diminishes, and the overall effect is a transfer of energy from the inductor back to the capacitor.

What is the role of a capacitor in an oscillator circuit?
Capacitors can affect the shape of the output waveform in an oscillator circuit. For example, in a square wave or pulse generator, capacitors help generate the desired waveform by charging and discharging at specific intervals. In a sine wave oscillator, capacitors are used to filter harmonics and ensure a sinusoidal output.
