A) \[{{V}_{3}}>{{V}_{2}}>{{V}_{1}}\]
B) \[{{V}_{2}}>{{V}_{1}}>{{V}_{1}}\]
C) \[{{V}_{3}}>{{V}_{1}}>{{V}_{2}}\]
D) \[{{V}_{1}}>{{V}_{2}}>{{V}_{3}}\]
Correct Answer: B
Solution :
S1 closed \[{{V}_{1}}=\frac{3R}{R+3R}\,\,\,V=\frac{3}{4}\,\,V\,\,=\,\,0.75\,\,V\] S2 closed \[{{V}_{2}}\,=\,\,\frac{6R}{R+6R}\,\,V=0.85\,\,R\] \[{{S}_{1}}\And \text{ }{{S}_{2}}\,\,both\text{ }closed\] \[{{V}_{3}}=\frac{2R}{R+2R}\,\,\,V=0.67\,V\] \[\therefore \,\,\,{{V}_{2}}>{{V}_{1}}>{{V}_{3}}\]You need to login to perform this action.
