Question

A piece of silver has a resistance of 6ohms what will be the resistance of a maganium wire of 1/3rd the length and 1/3rd the diameter if the p of magnium is 30 times of silver
​

Answer 1

Answer:

90 ohms

Explanation:

1/3 L = 1/3 R

1/3 D = 1/9 A

So,

R = 1/3*9*30*1

= 90 Ohm.

Resistance = 90 Ohm.
