Question

Calculate the resistance of a copper wire of length 2m and cross section area 1*10-3 Resistivity of the copper wire is 1.7*10-8.

Answer 1

Answer:

Explanation:

LENGTH=2 M

AREA=0.001 M²

RESISTIVITY=1.7*10^-8

RESISTANCE=?

RESISTANCE=RESISTIVITY*LENGTH/AREA

RESISTANCE=1.7*10^-8*2/10^-3

RESISTANCE=1.7*2.10^-5

RESISTANCE=3.4*10^-5 OHMS.
