Question

Consider the circuit shown in the figure.



Which of the following statements are correct ?

• A. Current through the battery is $5 \, A$
• B. Current through branch $AD$ is $2A$
• C. Current through branch $BC$ is $3A$
• D. The potential difference between points $D$ and $C$ is $4V$

Answer 1

Answer: (A)

By using the concept of Wheatstone bridge
$V_{D} \, - \, V_{C} \, = \, 0$
$\therefore $ $R_{e q}=\frac{12 \times 6}{12 + 6}=4 \, \Omega $
$\therefore $ $I_{b a t t e r y}=\frac{20}{4}=5 \, A$
