 Q:- Compute the electrical conductivity of a cylindrical specimen in a diameter of 10 min and 65 mm length in which a current of 0.01 A passes in an axial direction A voltage of 12 V is masured across two probes that are separated by 30 mm.

Also, Compute the resistance or the entire 65mm length of the specimen.

Answer : - 

Given , 

Diameter , d = 10 mm

Length ,      L = 65 mm

Current ,      I = 0.01 A

Voltage      V   = 12v

So, 

Hence the electrical conductivity of the  cylindrical specimen is 0.31847 and the resistance of the cylindricayspecimen of lenght 65 mm is 26  ohm
