Electric Circuits and Networks

INTRODUCTION

An electrical network is an interconnection of two-terminal elements and/or multiterminal elements. Two sets of laws govern the electrical behaviour of such a network. The first set comprises Kirchhoff's Current Law and Kirchhoff's Voltage Law. The second set comprises element relations for the two-terminal elements and multi-terminal elements. Element relationship encodes the electrical behaviour of the physical device that is being modelled by the two-terminal element model or the multi-terminal model in the form of a constraint between terminal voltage and terminal current variables. ‘Electric circuit’ and ‘electrical network’ mean more or less the same. However, the word network usually implies a complex interconnection of large ...
