Question

At OK, Germanium behaves as
(A) a conductor
(B(an insulator
(C) an intrinsic semiconductor
(D) an extrinsic semiconductor
​

Answer 1

Germanium behaves as an insulator ..at 0'k..

And it think its 0'k not Ok...

I hope u get it..

Answer 2

Hey Dear,

◆ Answer -

(B) an insulator

◆ Semiconductors -

• Substances that can act as both conductors as well as insulators depending on the conditions are called semiconductors.
• For example, Germanium, Silicon, etc.
• Semiconductors can be either intrinsic or extrinsic.
• At absolute zero of temperature i.e. 0 K semiconductors act as insulators.
• As temperature rises, conductivity of semiconductors increases.

Hope this helps you.
