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
Options
A.+1 V
B.- 1 V
C.+ 2 V
D.- 2 V
Solution
Applying Kirchhoff voltage law in the circuit is as shown in the figure below
∴ VA + 1 + 2(1) - 2 = VB
0 + 1 = VB (∵ VA = 0(Given))
VB = + 1V
