The resistance of several materials are shown in the table. Based on this, which material has the best conductivity? Material Resistance (ohms) Aluminum 0.0000000282 Carbon (Graphite) 0.000035 Germanium 0.46 Silicon 640
A. aluminum
B.Carbon (Graphite)
C.Germanium
D.Silicon

Respuesta :

Answer:

it is A aluminum

Explanation:

Answer:

Aluminium has best conductivity

So option (a) will be correct answer

Explanation:

We have given material resistance of of different material

Aluminium = 0.0000000282 ohm

Carbon = 0.000035

Germanium = 0.46 ohm

And silicon = 640 ohm

We know that resistance is the opposition in flow of current and conductivity of the material is inversely proportional to the resistance

So the material which has less Resistance will have high conductivity

As aluminium has less resistance so it will have high conductivity

So option (a) will be correct answer
