Procedure

Experiment Steps

Switch on the power for Kit. Set the potentiometer to minimum position. Switch on SW2 and observe the pulse across G.Check whether DC voltage is varying from 0-30V. Connections are made as shown in the circuit diagram. Now vary the frequency using to some point. Vary input voltage and note down the reading across load. Repeat from step6 for different values.

Note: If the connections are made wrong the kit may get damaged. Please switch off the kit when not in use.
