Question

1. switches are used to ________. a open or close current paths b control the level of resistance c protect a circuit from current flow d open the current path in the instance of an overload

Explanation:

Switches are electrical components that can be used to either open (break the circuit, stopping current flow) or close (complete the circuit, allowing current flow) the path of electric current in a circuit. They don't control resistance directly (resistors do that), don't primarily protect a circuit from current flow (fuses and circuit - breakers do that for overload protection), and opening the current path in case of an overload is the function of circuit - breakers or fuses, not the general function of a switch.

Answer:

A. open or close current paths
