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 ...

As engineering innovations continue to advance ultracapacitors, their enhanced performance capabilities are expected to hasten the convergence of batteries and ultracapacitors—strengthening the ...
