Question

A piece of wire of resistance R is cut into five equal parts, keeping same cross section area what will be the new resistance of each resistor.

• A. $\frac{R}{5}$
• B. 5R
• C. R
• D. $\frac{R}{2}$

Answer 1

The correct option is A $\frac{R}{5}$

We know that resistance of any resistor is directly proportional to the length of it, So, therefore, each resistor will become $\frac{R}{5}$.
