Which of following statements is wrong?

A

Resistance of a voltmeter is very high.

B

Resistance of an ammeter is very small.

C

Ammeter is always connected in parallel with a circuit element, current passing through which is to be measured.

D

Voltmeter is always connected in parallel with a circuit elements, voltage across which is to be measured.

Text Solution

Verified by Experts

The correct Answer is:
C
Because, an ammeter is a current meter, which always, is to be connected in series with a current current element, current passing through which is to be measured.
