Which option best describes the function of a switch?
A. An open switch prevents electric flow, and a closed switch allows electric
flow
B. An open switch strengthens electric flow, and a closed switch weakens
electric flow
C. An open switch allows electric flow, and a closed switch prevents electric
flow
D. An open switch allows electric flow, and a closed switch allows electric
flow

A

Explanation:

A switch is a part of a circuit that allows a connection to be made or broken. By convention, when the switch is "open", the connection is broken and therefore electric flow (current) cannot pass. On the other hand, when the switch is "closed", the connection is complete and electric flow can pass.
