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.

What role does a switch play in an electrical circuit?

• It acts as a power source.

• It acts as a gatekeeper.

• It acts as a conductor.

• It acts as an insulator.

What happens when a switch is flipped to the on position?

• The circuit is completed.

• The circuit is broken.

• The device is turned off.

• The current stops flowing.

What occurs when a switch is turned off?

• The circuit is completed.

• The current flows freely.

• The device is powered up.

• The circuit is broken.

Which type of switch allows you to adjust the brightness of a light?

• Rotary switch

• Push button switch

• Dimmer switch

• Toggle switch

Which of the following is a simple form of a switch?

• Rocker switch

• Slide switch

• Toggle switch

• Dimmer switch
