Answer:
Explanation:
Closed, Open, and Short Circuits
A closed circuit allows current to flow, but an open circuit leaves electrons stranded.
A switch in the open position disconnects the light bulb from the battery, creating an open circuit.
Closing the switch completes the conductive path in this flashlight, allowing electrons to flow.
An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance.
