A) V3 > V2 > V1
B) V2 > V1 > V3
C) V3 > V1 > V2
D) V1 > V2 > V3
Correct Answer: B
Solution :
In series : Potential difference µ R When only S1 is closed \[{{V}_{1}}=\frac{3}{4}E=0.75E\] When only S2 is closed \[{{V}_{2}}=\frac{6}{7}E=0.86E\] and when both S1 and S2 are closed combined resistance of 6R and 3R is 2R \ \[{{V}_{3}}=\left( \frac{2}{3} \right)E=0.67E\] Þ \[{{V}_{2}}>{{V}_{1}}>{{V}_{3}}\]
