ANSWER

The resistance of an electric wire of an alloy is 10 ohm . If the thickness of wire is 0.001 metre and length is 1metre .Find its resistivity

Posted by Tanishka Pardeshi 3 years, 2 months ago

CBSE > Class 10 > Science

2 answers

Preeti Dabral 3 years, 2 months ago

Resistance (R) = 10 Ω

Length (L) = 1 m

Diameter (D) = 0.001 m (mentioned as thickness)

The resistivity of an Electric Wire is given by the equation:

R = ρ * (L / A)

Resistivity is measured in Ω.m

Where, ρ is the resistivity of the wire

R is the resistance of the wire

L is the length of the wire

A is the area of cross section of the wire.

The equation is rearranged as

ρ = R * (A / L) ; where A = π r^2 … (π = 3.14)

Substituting the values,

A = 3.14 (0.0005)^2 …………D = r / 2 ; 0.001 / 2 = 0.0005

= 0.000000785 = 0.785 * 10^-6

ρ = 10 / (0.785 * 10^-6)

ρ = 0.785 * 10^-5 Ω.m
