I WONDER - What Does A Switch Do In A Circuit?

The video explains the function of switches in electrical circuits, acting as gatekeepers that control the flow of electricity. When a switch is turned on, it completes the circuit, allowing current to flow and power devices. Conversely, turning off the switch breaks the circuit, stopping the flow of electricity. The video also discusses various types of switches, including simple toggle switches and more complex dimmer switches that adjust light brightness.
