Question

Which is the equivalent resistance when resistors $3\Omega$ and $6\Omega$ are in parallel ?

• A. $9\Omega$
• B. $3\Omega$
• C. $2\Omega$
• D. $6\Omega$

Answer 1

Answer: (C)

$2\Omega$

Equivalent resistance is given by:
$\frac{1}{R_{eq}}=\frac{1}{3}+\frac{1}{6}=\frac{1}{2}{R}_{eq}=2\Omega$
