Question on: JSS1 Basic technology - Electrical Projects - Flashlight

The switch in a flashlight circuit controls the flow of electricity by opening or closing the circuit. When the switch is closed, it completes the circuit, allowing current to flow from the batteries to the light source, thus turning the flashlight on. Conversely, when the switch is open, it breaks the circuit, stopping the current flow and turning the flashlight off. This simple mechanism ensures that the user can easily control the operation of the flashlight. The switch is a crucial component, as it regulates the functionality and energy consumption of the flashlight.
