Question

Resistance of wire is 12 ohm what will the resistance when it length is double​

Answer 1

resistance also doubles as it directly proportional to the length

R=pL/A

so

R=24 Ohm

Answer 2

Answer:

Resistance is directly propotional to the length.if the resistance is 12 then length is 12 .if the length is doubled then resistance will also doubled.

so,

r=12ohm

doubled of resistance is 24 .(length is doubled)
