Relay vs Transistor - Difference between Relay and Transistor

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 the Difference between Relay and Transistor.

very good, thanks! I would add the fact that relays have also a switch bounce which produces a ripple in the signal when switched, which can may be an issue in sensible circuits (although capacitors can be enough in this case)

Hi There, Very nicely explained. Thank you so much.
