Electricity Field

Calculate the length of a constantin wire of diameter 0.6mm and resistivity 1.1x10^-6
ohm require to construct require of resistance 35 ohm

asked 11 months ago    

Answer

9.0 ohms

answered 11 months ago    

Answer

The formula for this operation is l = RA/p
Where
R = Resistance = 35 Ohms
A = Cross-sectional Area = 3.142(d/2)^2
Since d = diameter = 0.6mm = 0.0006m
A = 3.142(0.0006/2)^2 = 2.8278x10^-7

Assuming from what you stated above you mean
p = Resistivity = 1.1x10^-6 Ohm-meter

L = (35(2.8278x10^-7))/1.1x10^-6
L = 8.9975m
Therefore, the length of the wire is 8.9975m approximately 9m.
