Common Terms used in Circuit Theory

A circuit is a closed conducting path through which an electrical current either flows or is intended to flow. A circuit consists of active and passive elements.

Parameters are the various elements of an electrical circuit (for example, resistance, capacitance, and inductance).

Linear circuit – a circuit in which the parameters are constant with time, do not change with voltage or current, and obey Ohm’s law. In a non-linear circuit the parameters change with voltage and current.

A passive network is a one which contains no source of EMF.

An active network is a one which contains one or more sources of EMF.

A bilateral circuit is one whose properties or characteristics are same in either direction of current. Example: the usual transmission line is bilateral.

A unilateral circuit is that circuit in which properties or characteristics change with the direction of operation. Example: a diode rectifier can rectify only in one direction.

A Node is a point in a circuit where two or more circuit elements are connected together.

Branch is a part of a network which lies between two nodes.

Loop is a closed path in a circuit in which no element or node is encountered more than once.

Mesh is a loop that contains no other loop within it.
