Question

In the given circuit, the value of current is

• A. 12 ampere
• B. 11 ampere
• C. 0.5 ampere
• D. Zero

Answer 1

Answer: (A)

12 ampere

All resistors are in parallel

$\frac{1}{R_P}=\frac{1}{3}+\frac{1}{6}+\frac{1}{1}=\frac{2+1+6}{6}=\frac{9}{6}$

$R_P=\frac{6}{9}=\frac{2}{3}\Omega$

$I=\frac{v}{R_P}=\frac{8}{2/3}=\frac{8}{2}\times 3=12A$

Hence, option $\left(A\right)$ is correct answer.
