Question

Which of the following is not correctly matched?
A. Ammeter

B. Voltmeter

C. Resistor

D. Battery

Answer 1

Hint:To solve this we need to know the basic sign used in an electric circuit.First we have to go term by term. If we first option, an ammeter is used to measure current similarly voltmeter measure the voltage of the circuit, resistance which implements electric resistance and battery is a source of electric power.

Complete step by step answer:
Ammeter:It is a measuring instrument that is used to measure the current flowing through the circuit. It is usually connected in series with the circuit in which we have to measure our current.
Symbol:

Voltmeter:It is an instrument which is used to measure the potential difference between any two points in an electric circuit and it is connected in parallel to that device.
Symbol:

Resistor:It is a passive two terminal electronic component that implements electric resistance in our circuit. It is used in the circuit so as to reduce current flow, adjust signal labels and terminate the transmission line.
Symbol:

Battery:It is a device that stores chemical energy and converts it into electrical energy which we use in out=r electric circuit as a source of electric power. This produces flow of electrons due to which it provides an electric current in our circuit.
Symbol:

Hence from the above discussion the only option which is not matched is option (C).

Note:Electric circuit is a conductive path for flow of electric current. Remer that an electric circuit consists of all the devices that give energy to the charged particle and can measure the change in the circuit. These electronic symbols are used to represent various electrical devices in simplified form or in picturized form. And the incorrect option symbol is of bulb.
