MCQ
When a battery is connected to a $P$ - type semiconductor with a metallic wire, the current in the semiconductor $(predominantly)$, inside the metallic wire and that inside the battery respectively due to
  • Holes, electrons, ions
  • B
    Holes, ions, electrons
  • C
    Electrons, ions, holes
  • D
    Ions, electrons, holes

Answer

Correct option: A.
Holes, electrons, ions
a
(a) Charge carriers inside the $P$ - type semiconductor are holes $(mainly)$. Inside the conductor charge carriers are electrons and for cell ions are the charge carriers.
