Verification of Compensation Theorem

Procedure:

Experiment Part Select:

Case 1:
Set the voltage (say V1=100V), internal resistance (say Rint=50ohm) and load resistance (RL). Simulate the circuit and observe the current I.

Case-2:
Change RL by Δ RL. Δ RL can change upto +/- 2% of RL. Simulate the circuit and observe the load current.

Case-3: Simulate the circuit. Observe the varying current (difference between case 1 and case 2) in compensating circuit.

Now after one observation go to Case 1 again and change the values of Rint and RL (through the up and down arrow keys in individual input boxes)and follow the above steps for getting another observation.

N.B.:- All the resistances are in ohms.
