6 FAQs about [How capacitors control oscillating current]

How many Ma does a capacitor have in an oscillating LC 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?

What is the maximum charge on a capacitor in an oscillating LC circuit?

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.

What happens when a capacitor is closed?

This energy is When the switch is closed, the capacitor begins to discharge, producing a current in the circuit. The current, in turn, creates a magnetic field in the inductor. The net effect of this process is a transfer of energy from the capacitor, with its diminishing electric field, to the inductor, with its increasing magnetic field.

What happens when a capacitor is fully charged?

When the capacitor is fully charged there is a potential difference between its poles and that creates a current. This current would create a magnetic field that is changing in the Inductor (because the current changes due to the capacitor), creating an EMF in the circuit.

How does an oscillator work?

This is made possible due to the nature of the reactive components – the capacitors and inductors – within the oscillator circuit. When a current is applied to these components, it causes a change in the charge or magnetic field, which in turn generates an oscillating voltage.

Why do oscillators use smaller capacitors?

In our oscillator configuration, you can’t get rid of this, but having larger resistors will reduce the amount of waste. So, in short, if you have higher-valued resistors to compensate, your circuit will waste much less current by using smaller capacitors. In this chapter, we learned the following: 1.
