The potential difference across A and B points of circuit is (assume above circuit is a part of some network and left over for long time in connection)

A)  88 volt                 

B)  60 volt

C)  8 volt                   

D)  20 volt

Correct Answer: A

Solution :

A steady start circuit can be drawn as \[{{V}_{A}}-20-8-60={{V}_{B}}\] \[\Rightarrow \,{{V}_{A}}-{{V}_{B}}=88\] volt
