What is electrical network?

The interconnection of electrical components like resistors, inductors, semiconductors devices, transformers and sources of e.m.f. is called as a network. The network consist a closed loop, which provides return path for the current. A network may contain one or more circuit elements. It has two or more terminals for making connection with other circuits.

Types of networks :

There are two types of networks which are given below,

• One port network.
• Two port network.

One port network

The network which has one pair of terminal is called one port network. It helps to reduce the complexity of circuit analysis. In many common electronic devices and circuit blocks such as transistors, amplifiers, electronic filters, and transformers are analyzed in terms of ports. A series, parallel combination of resistors and  capacitors are example of one port network.

Two port network

The network having two pairs of terminal is called a two port network. An amplifier, attenuator, filter, transformer are examples of two port network.
