By mistake, a voltmeter is connected in ...

By mistake, a voltmeter is connected in series and an ammeter is connected in parallel, with a resistance in an electrical circuit. What will happen to the instruments?

A

Voltmeter is damaged

B

Ammeter is damaged

C

Both are damaged

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
A voltmeter has very high resistance. If it is connected in series, in the circuit, the total resistance in the circuit will increase and the current will decrease connsiderably. As there is no danger of the flow of large current in the circuit, both the instrument will not be damaged.
