The forward current through a semiconductor diode circuit is due to:
Correct answer: C. Majority carriers
- A. Minority carriers
- B. Holes
- C. Majority carriers
- D. Electrons
Explanation
Forward current in a diode is driven by majority carriers (electrons in N-type, holes in P-type) moving across the junction.

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.
