The self-inductance of an circuit is 0.20 mH. The circuit’s capacitance is 5.0 pF. What is the angular frequency of the current in the circuit?
In an oscillating circuit, the maximum charge on the capacitor is C and the maximum current through the inductor is 8.0 mA.
What is the period of the oscillations?
How much time elapses between an instant when the capacitor is uncharged and the next instant when it is fully charged?
An circuit in an AM tuner (in a car stereo) uses a coil with an inductance of 2.5 mH and a variable capacitor. If the natural frequency of the circuit is to be adjustable over the range 540 to kHz (the AM broadcast band), what range of capacitance is required?
