Answer:
The correct answer is the option D. Hence a device that uses the energy is missing in the circuit.
Explanation:
Normally the circuit is something/picture which graphically represents the electrical circuit. It is generally a closed pathway containing different devices.
A general electric circuit includes:
- A voltage source: An energy source Like battery.
- A switch: A button which is used to on/off the circuit. It actually completes the circuit when it is on and incomplete the circuit when it is off.
- A device which uses current: There is a bulb or a device which indicates the completeness of circuit. For example when a bulb is on in a circuit it shows that the current is flowing in circuit.
So in above circuit there are first two components missing third one which as a indicator or device through which current will pass.
