Question
In the electric network shown, when no current flows through the 4Ω resistor in the arm EB, the potential difference between the points A and D will be :
Options
A.6 V
B.3 V
C.5 V
D.4 V
Solution
Let
VD = 0V
VE = 0V
VB = −4V
VA = 5V
VA − VD = 5V
Option (3)
VD = 0V
VE = 0V
VB = −4V
VA = 5V
VA − VD = 5V
Option (3)
