PROCEDURE:
1. Connect the circuit as shown in figure. A and note the reading of ammeter (I1)
for constant DC sources.
2. Now connect the circuit as shown in figure B. and note the reading of ammeter
(I2) for constant AC source voltage.
3. Now connect the circuit as shown in figure.1 and note the reading of ammeter
(I1) for same values of voltage which are applied in step1 and 2.
4. Tabulate the reading of ammeter as shown below:
5. Verify superposition theorem by equation I1+I2=I3.
6. Repeat the experiment (step 1to 5) for different constant values of source
voltage (at least 5 values)
