Question

Find the current supplied by the battery in the circuit as shown in figure.

• A. 9 A
• B. 4 A
• C. 12 A
• D. 3 A

Answer 1

The correct option is A 9 A

Here the three resistors are in parallel as shown in figure.
The equivalent resistance is $R_{eq}=(1/8+1/6+1/12{)}^{-1}=(8/3)\Omega$
The current drawn from supply is $I=\frac{V}{R_{eq}}\frac{24}{\left(8/3\right)}=9A$
