Question

A wire of resistance 16 ohm is cut into four equal pieces and connected in parallel equivalent resistance of the combination is

Answer 1

I hope it is right answer

Answer 2

Given that,

Resistance of wire, R = 16 ohms

To find,

The equivalent resistance of the combination.

Solution,

It is mentioned that the wire of resistance 16 ohm is cut into four equal pieces and connected in parallel. The resistance of each part is R/4 or 4 ohms. Then in parallel equivalent resistance is given by :

$\dfrac{1}{R}=\dfrac{1}{4}+\dfrac{1}{4}+\dfrac{1}{4}+\dfrac{1}{4}\\\\R=1\ \Omega$

So, the equivalent resistance of the combination is 1 ohm.
