Question

In the given circuit, Voltmeter reading is :

• A. 0.5 Volt
• B. 1 Volt
• C. 2 Volt
• D. 4 Volt

Answer 1

Answer: (C)

2 Volt

According to the given circuit, $R_{eq}=100+\frac{200\times 100}{200+100}=500/3$

$I=\frac{5X3}{500}=\frac{3}{100}$ Amp

Voltmeter (having $200$ ohm resistance) and the $100$ ohm resistance are parallel to each other therefore,

$I_{100}\times 100=I_{200}\times 200$

$I=I_{100}+I_{200}$

On solving, $I_{200}=I/3$

$V=\frac{3}{100}\times \frac{1}{3}\times 200=2$ Volts. Hence $V=2$ Volts
