Electrical Circuits
An electrical network is an interconnection of electrical elements linked together in a closed path so that an electric current may flow continuously.
NETWORK An electrical network is an interconnection of electrical elements linked together in a closed path so that an electric current may flow continuously. Classification of a network is done based on the type of elements being used in that network. The operational characteristics of a network depend on the behaviour of its elements. (1) Active network : A network which contains active elements is known as active network. Example: batteries, generators, transistors, etc. (2) Passive network : Element which absorb the energy are known as passive elements. A network containing only passive elements is known as passive network. Example resistors, inductors and capacitors. (3) Unilateral network : A network whose operational behaviour is dependent on the direction of flow of current through various elements is known as unilateral network. Elements like semiconductor diode, which allow the current to pass through them only in one direction. (4) Bilateral network : A network whose behaviour is same irrespective of the direction of flow of current through the circuit elements is known as bilateral network. Passive elements that allow the current to pass through them in both directions are known as bilateral elements. (5) Lumped network : Networks consisting of elements which can be physically separated are known as lumped networks. Most of the networks are lumped in nature and consists of R, L, C and sources. (6) Distributed network : Networks consisting of elements which cannot be physically seperable for analysis purpose, is called distributed networks. Networks, like transmission lines, having inseparable elements are known as distributed networks. (7) Linear network : The network whose parameters are constant. They do not change with voltage or current, is called linear network. (8) Non-linear network : The network whose parameters are change with voltage (or) current, is called non-linear network.
