The statement is true. When a plug key is closed, electric circuit is completed.
Explanation:
- Plug key is an electronic component whose function is similar to that of a switch.
- A small metallic key is present which when pressed, switch turns on and when we remove it from its base the circuit gets off.
- When a plug key is closed, the path for electricity flow is made and when it is open, the path for current flow is broken.
- A complete electric circuit refers to a closed working circuit. When an electric circuit is closed and complete, it is open to allow current flow through it.
So, a closed plug key completes an electric circuit.
