what is distributed-element circuit? They are electrical circuits composed of lengths of transmission lines or other distributed components. what are some active components in it? diodes, transistors mention a few of the circuit's disadvantages? It takes up more space than lumped-element circuits and is problematic in hand-held mobile devices which has limited space.

Transistor [SEP] Introduction
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits. Austro-Hungarian physicist Julius Edgar Lilienfeld proposed the concept of a field-effect transistor in 1926, but it was not possible to actually construct a working device at that time.
