which device manages the flow of current in an electric circuit?\nthe wire\nthe switch\nthe battery\nthe light bulb
Answer
Brief Explanations:
- A wire is a conductor that allows current to flow but does not manage its flow.
- A switch can open or close a circuit, thus controlling (managing) the flow of current.
- A battery is a source of electrical energy (provides voltage to drive the current), not a manager of current flow.
- A light - bulb is a load that uses electrical energy (converts it to light and heat), not a device for managing current flow.
Answer:
the switch
