MHT CET Physics question

Not in JEE Advanced syllabus

Fermi energy is the

(A)minimum energy of electrons in a metal at 0 K
(B)maximum energy of electrons in a metal at 0 KCorrect
(C)minimum energy of electrons in a metal at 0°C
(D)maximum energy of electrons in a metal at 0°C

Answer: (B)

Solution

At 0 K the electrons fill the allowed levels from the bottom up and the highest filled level is the Fermi level, so Fermi energy is the maximum energy of the
