Choose an option
Show full solutionCorrect option: A
Correct answer
Aconnect resistor of , in series with voltmeter.
Step-by-step explanation
Let the maximum current for full-scale deflection of the voltmeter be .
To increase the measuring range to V, a resistance must be connected in series with the voltmeter.
Thus, a resistor of should be connected in series with the voltmeter.
Answer: connect resistor of , in series with voltmeter.
To increase the measuring range to V, a resistance must be connected in series with the voltmeter.
