In the circuit given in figure current is different branches and the value of the one resistor are shown. The potential at point B with respect to A is?
Option: 1 -1 V
Option: 2 + 1V
Option: 3 +2V
Option: 4 2V
Correct Answer: 2) + 1V
At C,
i+1=2
Or. i=1 A
Let VA=0, then VC=1V
VD=VC+2 x i=3V
VB=VD-2=1V
So,
Study 40% syllabus and score up to 100% marks in JEE
