for RLC network.

2. Time response of first order RC/RL network for periodic non-sinusoidal inputs – time constant and

steady state error determination.

3. Two port network parameters – Z-Y Parameters, chain matrix and analytical verification.

4. Verification of Superposition and Reciprocity theorems.

5. Verification of maximum power transfer theorem. Verification on DC, verification on AC with Resistive

and Reactive loads.

6. Experimental determination of Thevenin’s and Norton’s equivalent circuits and verification by direct test.

 

PART – B

1. Magnetization characteristics of D.C. Shunt generator. Determination of critical field resistance.
