Question

This circuit diagram lacks a basic feature of a circuit.

Which basic feature is missing from the circuit?

A) an energy source
B) conducting wires
C) a switch
D) a device that uses energy

Answer 1

The correct answer is the option D. Hence a device that uses the energy is missing in the circuit.

Step-by-step 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.

Answer 2

The basic feature that is missing from the circuit is D) a device that uses energy
