Question

Consider the circuit shown in the figure.



Which of the following statements are correct ?

• A. Current through the battery is $5A$
  
  
• 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
$V_D-V_C=0$
$\therefore$ $R_{eq}=\frac{12\times 6}{12+6}=4\Omega$
$\therefore$ $I_{battery}=\frac{20}{4}=5A$
