JEE Main 2015 — Current Electricity Question with Solution

JEE Main 2015 (11 Apr Online)

Question

In the electric network shown, when no current flows through the 4 Ω resistor in the arm EB, the potential difference between the points A and D will be:

Choose an option

Show full solutionCorrect option: A
Correct answer
A5 V

Step-by-step explanation



Assuming potential at B = 0, then w.r.t. B the potential of other points are as shown in figure then

So, VA=9 V and VD=4 V

∴VA-VD=9-4=5 V
