Look at almost any circuit, and it’s nearly sure that there will be a capacitor included in it. These two-terminal electrical components rank alongside resistors.

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

Capacitors connected in parallel, the total capacitance is the sum of the individual capacitors’ capacitances. If two or more are connected in parallel, the effect is that of a single equivalent ...
