In a n-type semi conductor there are:
Correct answer: B. Immobile positive ions
- A. Holes as majority carrier
- B. Immobile positive ions
- C. Immobile negative ions
- D. None of these
Explanation
In an N-type semiconductor, the density of negative charge carriers is higher; therefore, it has immobile positive ions, and electrons are the majority charge carriers.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
