Q. In the previous question, if the direction of $i$ is reversed, $(V_{B} - V_{A})$ will be
A) 20 V
B) 15 V
C) 10 V
D) 5 V
Explanation
(b) When the direction of current is reversed, moving from $B\ to\ A.$
$V_{B} - V_{A} = \left\lbrack 5 \times 10^{- 3}\left( - 10^{3} \right) + 15 + 1 \times 5 \right\rbrack$
= 15 volt
