Question

In the circuit shown in the figure, if the potential at point $A$ is taken to be zero, the potential at point $B$ is

• A. +1 V
• B. -1 V
• C. +2 V
• D. -2 V

Answer 1

Answer: (A)

+1 V

Answer 2

By $KVL$ along path $ACDB$
$V _{ A }+1+(1)(2)-2= V _{ B }$
$0+1= V _{ B }$
$\Rightarrow V _{ B }=1$ volt
