This video explains how to use a transistor to control a relay, which can then be used to switch on and off electrical appliances. The video uses a DC motor as an example, but the same principle can be applied to other appliances. The video includes a practical demonstration of the circuit, showing how to connect the components and how the circuit works.

This video demonstrates how to use an NPN transistor as a small relay. The creator explains the limitations of this method, including the maximum current draw, and then walks through the circuit setup using a 12-volt supply for LEDs and a 3.5-volt battery to control the transistor. The video concludes with a practical demonstration of the circuit in action.
