R eq =200+(300 × 600/300+600)+100 =500 Ω I =(100/500)=(1/5) amp I 600=((1/600)/(1)300+(1)600 × (1/5) =(1/15) amp Reading of volt meter = I R /600)=(1/15) × 600 =40 V

Q. The reading of voltmeter is

50 V

60 V

40 V

80 V

$R_{e q} = 200 + \frac{300 \times 600}{300 + 600} + 100$
$= 500 Ω$
$I = \frac{100}{500} = \frac{1}{5}$ amp
$I_{600} = \frac{\frac{1}{600}}{\frac{1}{300} + \frac{1}{600}} \times \frac{1}{5}$
$= \frac{1}{15}$ amp
Reading of volt meter
$= I R_{600} = \frac{1}{15} \times 600$
$= 40 V$
