Objective of this experiment:
To verify that the SCR is basically a rectifier which conducts current in only one direction. However, the device can be made to conduct (turn "ON") or stop conducting (turn "OFF") and therefore provide a switching action that can be used to control electrical current. To draw the V-1 characteristics by taking different readings of anode voltage and anode current to get the forward break over (VF) and holding current (IH).

Built in regulated supply + 15V/300mA.
Input Supply: 230 VAC/50Hz mains operated.
