INTRODUCTION:
An Electric circuit is an interconnection of various elements in which there is at least one closed
path in which current can flow. An Electric circuit is used as a component for any engineering system.
The performance of any electrical device or machine is always studied by drawing its electrical
equivalent circuit. By
simulating an electric circuit, any type of system can be studied for e.g.,
mechanical, hydraulic thermal, nuclear, traffic flow, weather prediction etc.
All control systems are studied by representing them in the form of electric circuits. The analysis, of
any system can be learnt by mastering the techniques of circuit theory.
