Question

A wire has resistance $12\Omega$. It is bent in the form of a circle. The effective resistance between the two points on any diameter is equal to

• A. $12\Omega$
• B. $6\Omega$
• C. $3\Omega$
• D. $24\Omega$

Answer 1

The correct option is C $3\Omega$

Equivalent resistance of the following circuit will be
$R_{eq}=\frac{6}{2}=3\Omega$
