Calculation of Length of Wire
Given:
- Resistivity of wire material = 44 x 10^-8 ohm m
- Resistance of wire = 14 ohm
- Diameter of wire = 1 mm
Formula:
Resistance of wire = (Resistivity x Length) / Area of cross-section of wire
Area of cross-section of wire = (π x Diameter^2) / 4
Solution:
Area of cross-section of wire = (π x 1^2) / 4 = 0.785 mm^2 = 7.85 x 10^-7 m^2
Resistance of wire = (44 x 10^-8 x Length) / (7.85 x 10^-7)
Length of wire = (Resistance of wire x Area of cross-section of wire) / Resistivity of wire
Length of wire = (14 x 7.85 x 10^-7) / 44 x 10^-8
Length of wire = 2.4875 m
Answer:
The length of the wire is 2.4875 m.

Resistivity=44×10^-8ohm m
resistance=14ohnm
area=πr^2 = 22/7×|/4×10^8
l=r×a/resistivity
=14×22/28×10^8÷44×10^-8
=25m
resistance=14ohnm
area=πr^2 = 22/7×|/4×10^8
l=r×a/resistivity
=14×22/28×10^8÷44×10^-8
=25m
