A) An ammeter is connected in series in a circuit and the potential difference across it is small
B) An ammeter is connected in series in a circuit and the current through it is negligible
C) A voltmeter is connected in parallel in a circuit and the current through it is negligible
D) A voltmeter is connected in parallel in a circuit and the potential difference across it is maximum
Correct Answer: B
Solution :
A galvanometer can be converted into a voltmeter by connecting a high resistance in series with it, while it can be converted into ammeter by connecting a low resistance in its parallel. Ammeter is always connected in series with the source and current through it is always maximum, so statement is wrong.
