Question

The reading of an ideal Voltmeter connected across R in the circuit shown below is:

• A. 1V
• B. 2V
• C. 3V
• D. 4V

Answer 1

The correct option is B

2V

For complete circuit

V = IR

6 = (0.02) (200 + R)

$\Rightarrow$ R = 100 $\Omega$

$\Rightarrow$ R Reading of voltmeter = IR = (0.02) (100) = 2V
