Describe the opposition to the flow of charge carries by resistors, capacitors, inductors.
If an inductor and a capacitor are connected in parallel with each other, and then briefly energized by
connection to a DC voltage source, oscillations will develop as energy is exchanged from the capacitor to
inductor and vice versa. These oscillations may be viewed with an oscilloscope connected in parallel with
the inductor/capacitor circuit. Parallel inductor/capacitor circuits are commonly known as tank circuits.
Figure 4 below shows a commonly used tank-circuit.

A tank circuit's natural frequency, called the resonant frequency, is determined by the size of the inductor
and the size of the capacitor, according to the following equation:

2n √LC
where fis the frequency, given in Hertz (Hz). Ideally, the oscillations produced by a tank circuit continue
indefinitely. Realistically, oscillations will decay in amplitude over the course of several cycles due to the
resistive and magnetic losses of the inductor.
