Types Of Electrical Circuits There are basicly three types of basic electronic circuits a Series Circuit, Parallel Circuit, and Series Parallel Circuit this is a combination of both series and parallel circuits.
A semiconductor diode, the most common type today, is a crystalline piece of semiconductor material with a pân junction connected to two electrical terminals. A vacuum tube diode has two electrodes, a plate (anode) and a heated cathode. Semiconductor diodes were the first semiconductor electronic devices. semiconductor diode, the most common type today, is a crystalline piece of semiconductor material with a pân junction connected to two electrical terminals.
