Question

what will be the length of the Silver wire of resistance of 6 ohm if the length of a similar wire is 80 cm and has resistance 3 Ohm

Answer 1

Hey there !

This can be solved by Ratio and Proportions method

Wire Length = 80 cm ; Resistance = 3 ohms

Wire Length = x cm ; Resistance = 6 ohms

Cross multiplying we get,

=> 80 × 6 = x × 3

=> x = 80 × 6 / 3

=> x = 80 × 2

=> x = 160 cm

Hence the length of wire having 6 ohms resistance is 160 cm.

Hope my answer helped !
