Which device manages the flow of current in an electric circuit?

the wire
the switch
the battery
the light bulb

the correct answer is: the switch

The answer is the switch.

Explanation:

Electric current is the movement of electric charges (electrons) through a conduit. That is, it is a flow of electrons. An electric circuit is the path that an electric current travels.

The wire is the conductor, that is, it carries the current to the other components of the circuit. The wires form the wires.

The switch is the control device that allows or prevents the passage of electric current through a circuit. When the switch is on, the current flows through the circuit and when the switch is off, the circuit breaks and the current does not flow.

The battery is the electric current generator. It is the source of energy that generates a voltage between its terminals making electrons travel through the circuit.

The light bulb is responsible for receiving and transforming electrical energy into another type of energy, such as light.

So, the answer is the switch.
