Question

Find the resistance of a nichrome of length 1 m and area of cross section 2 mm^2 . The resistivity of the nichrome wire is 100 × 10^-6 m

Answer 1

100 ohm will be the resistance

Answer 2

Resistance =specific resistance *length /area
=100*10 power -6*1/2/10 power 6
=100 ohm
hope it helps
