Question

If the resistance of a certain copper wire is 1 Ω, then the resistance of a similar nichrome wire will be about:

(a) 25 Ω
(b) 30 Ω
(c) 60 Ω
(d) 45 Ω

Open in App

Solution

(c) 60 Ω

If the resistance of a certain copper wire is 1 Ω, the resistance of a similar nichrome wire will be about 60 Ω because the resistivity of nichrome is 60 times the resistivity of copper.
