Question

A part of an electric circuit is shown in the figure. If the reading of the voltmeter is 100 V and the resistance of the voltmeter is 200 $\Omega$, then the value of the resistance $R_{2}$ is}

• A. 125 $\Omega$
• B. 75 $\Omega$
• C. 25 $\Omega$
• D. 50 $\Omega$ \bigskip

Hint:

Whenever a voltmeter has finite resistance, do not treat it as an ideal instrument. It draws current and behaves like a resistor connected in parallel with the circuit element across which it is connected.
