Question

$15\Omega ,10\Omega$ and $5\Omega$ resistor are connected in parallel. What is the equivalent resistor of this connection?

• A. A less than $5\Omega$
• B. More than $30\Omega$
• C. $30\Omega$
• D. More than $15\Omega$

Answer 1

The correct option is A A less than $5\Omega$

$R_{eq.}=\frac{\frac{50}{15}\times 15}{\frac{50}{15}+15}$

$\Rightarrow R_{eq}=\frac{50\times 15}{275}=2.72\omega$

Hence, the answer is $2.72\omega .$
