Q. The potential difference $V_{ A }-V_{ B }$ between points $A$ and $B$ for the circuit segment shown in figure-3.350 at the given instant is :
Current Electricity
A
$12 V$
B
$-12 V$
C
$6 V$
D
$-6 V$
Solution:
Writing equation of potential drop from terminal $A$ to $B$ gives
$V_{ A }-6-3 \times 2+\frac{9}{1}-3 \times 3=V_{ B }$
$V_{ A }-V_{ B }=12\, V$
