Question

What is the equivalent resistance in the given circuit?

• A. $35\Omega$
• B. $560\Omega$
• C. $70\Omega$
• D. $400\Omega$

Answer 1

The correct option is A $35\Omega$

The resistances in the given question are in parallel. So, the equivalent resistance of the system will
become $\frac{1}{R_{eq}}=\frac{1}{140}+\frac{1}{140}+\frac{1}{140}+\frac{1}{140}$
$\Rightarrow R_{eq}=\frac{140}{4}=35\Omega$
