Question

What is the current drawn from the source in the given circuit ?

• A. 2 A
• B. 1.5 A
• C. 4 A
• D. 3 A

Answer 1

The correct option is C 4 A

to calculate current we need to know equivalent resister in circuit.

$R_{eq}=3\Omega +(6\Omega \parallel 6\Omega \parallel 6\Omega )R_{eq}=3+(\frac{1}{6}+\frac{1}{6}+\frac{1}{6})R_{eq}=3+2=5\Omega AndV=IRI=\frac{20}{5}=4A$
