14.2 Mutual Inductance. Inductance is the property of a device that expresses how effectively it induces an emf in another device. Mutual inductance is the effect of two devices inducing emfs in each other. where M is defined to be the mutual inductance between the two circuits and the minus sign is due to Lenz''s law.

One of the main differences between a capacitor and an inductor is that a capacitor opposes a change in voltage while an inductor opposes a change in the current. Furthermore, the inductor stores energy in the form of a magnetic field, and the capacitor stores energy in the form of an electric field. In this article, learn more differences ...

The expression in Equation 8.4.2 8.4.2 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference V = q/C V = q / C between its plates.

To store that amount of energy in a capacitor, you would need a 56 millifarad capacitor at 230V. It would take a 1 henry inductor at about 60A to hold that amount of energy. Each part (L and C) have to be capable of storing the total amount since they are shuttling it back and forth all the time.

Antennas and Resonant Circuits (Tank Circuits) PDF Version. Antennas serve to propagate AC waves into the surrounding space as well as to capture the waves for conversion back into an AC signal. Resonator circuits convert a DC source into an oscillating wave. Capacitors store energy in electric fields, proportional to the square of voltage.
