Question

By error, a student places moving-coil voltmeter $V$ (nearly ideal) in series with the resistance in a circuit in order to read the current, as shown. The voltmeter reading will be

• A. 0
• B. 4 V
• C. 6 V
• D. 12 V

Answer 1

The correct option is D 12 V

As shown in figure, moving-coil voltmeter V (nearly ideal) is placed in series with the resistance in a circuit. Thus it is in parallel to the battery, hence will measure voltage across it i.e. 12V
