Question

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. 3 V
• B. 4 V
• C. 5 V
• D. 6 V

Answer 1

The correct option is C 5 V


Applying kvl along ABED of $i_1=0$
$V_A-9+4=V_D\Rightarrow V_A-V_D=5V$
