### Electrical Circuit Theory

Rationale:

• Electric circuit analysis is the process of finding the voltages across, and the currents through, every component in the network. There are many different techniques for calculating these values.
• This subject is course on the basics of Network Analysis, introduction to network elements and explained all the possible method for finding voltage and current across any network Component with DC, single phase AC and 3 phase ac sources.
• It aims at making the student conversant with different techniques of solving the problems in the field of Electric circuits and analysis.

Objectives:

The students should be able to:

• Explain the concept of electrostatics and capacitance effect and analyze different Circuit Elements, Energy Sources and analysis of Network by Kirchhoff’s Laws.
• Analyze the concept of Node and Mesh Analysis; analyze different theorems for dc circuits.
• Analyze single phase circuits using resistor, inductor & capacitor elements.
• Explain and analyze series and parallel resonant behavior of a circuit.
• Analysis of balanced three phase ac circuit and three phase power measurement
