Question 160 of 380

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

A$5V$B$3V$C$4V$D$6V$

Show answer and solution▾

Answer: (A) $5V$

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

So, ${V}_{A}=9V$ and ${V}_{D}=4V$

$∴{V}_{A}-{V}_{D}=9-4=5V$
