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.

A circuit is a closed loop containing various components. Electrical current flows around the circuit. Scientists use symbols to represent the different components in a circuit. Symbols are simplified ...
