Question

Which one of the following material is non-ohmic:
A. Gold B. Germanium C. Copper D. Silver​

Answer 1

• The conductors which follow the ohms law are called the ohmic conductors. That is, the resistance will remain the same on changing the current and current.
• Non- ohmic conductors are conductors which do not follow the ohms law. That is, resistance changes with the changing current and voltage.
• P-N junction diodes made up of semiconductor materials are also said to disobey ohm’s law.
• We are all well aware that Germanium is widely used in semiconductor materials.  
• This means that the graph will not be linear, and hence they are said to be non-ohmic conductors.
• Silver, gold, and copper are ohmic whereas Germanium is non-ohmic.

Answer 2

Answer:

Germanium

Explanation:

because it is metalloid
