Relay vs Transistor - Difference between Relay and Transistor
The difference between the Relay and transistor is explained. When the Base voltage of the transistor is zero (or negative), the transistor is cut-off and acts as an open switch. In this condition no Collector current flows. And the relay coil is de-energized because being current devices, if no current flows into the Base, then no current will flow through the relay coil.
In this video we will go to learn Difference between Relay and Transistor.
