8.5: Capacitor with a Dielectric

This equation tells us that the capacitance (C_0) of an empty (vacuum) capacitor can be increased by a factor of (kappa) when we insert a dielectric material to completely fill the space between its plates. Note that Equation ref{eq1} can also be used for an empty capacitor by setting (kappa = 1). In other words, we can say that the ...

Capacitors in Series and Series Capacitor Circuits

One important point to remember about capacitors that are connected together in a series configuration. The total circuit capacitance ( C T ) of any number of capacitors connected together in series will always be LESS than the value of the smallest capacitor in the series string. In our example above, the total capacitance C T was calculated as being 0.055μF but …

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.
