## Electrical Circuit Analysis – II

### Preamble :

This course aims at study of 3 section systems, transient analysis, network synthesis and Fourier analysis for the longer term study and analysis of power systems.
Learning Objectives:

• to review the ideas of balanced and unbalanced three-phase circuits.

• to review the transient behaviour of electrical networks with DC, pulse and AC excitations.

• to review the performance of a network supported input and output excitation/response.

• to grasp the conclusion of electrical network perform into electrical equivalent passive parts.

• to grasp the appliance of series and fourier transforms for analysis of electrical circuits.

#### UNIT-I
