Lab #7- SCR Checker was used to see how an SCR works as a gated diode. When the power supply was connected and the wire coming off of the 1 K Ohm resistor was touched to the collector, the Led lit up and stayed lit up until the power supply was disconnected. This shows how the "gate" of the SCR was opened when electricity passed through it and as long as the electricity remained, it did not close.
