Two wires made of same material have equal length and radius of one of them is twice that of the other. Find the ratio of their resistances.

Text Solution

Verified by Experts


`therefore (R_(1))/(R_(2))=((rho l)/(pi r^(2)))/((rho l)/(4pi r^(2)))=4, therefore` The ratio of the resistances of the thin and the thick wires = 4 : 1
