The potential difference between A and B in the following figure is:

A) 32V                 

B) 48V    

C) 24V                 

D) 14V

Correct Answer: B

Solution :

\[{{\operatorname{V}}_{A}}-{{V}_{B}}=2\times 6+12+9\times 2-4+2\times 5\] \[=12+12+18-4+10\] \[=48V\] \[\therefore  Sign conventions\] For potential drop = +ve For potential rise = -ve In current direction = +ve In reverse to current = -ve
