Assertion: In n-type semiconductors, electrons are the majority charge carriers and holes are the minority charge carriers. Reason: N-type semiconductor is electrically neutral.
Correct answer: B. Both Assertion & Reason are true, but the reason does not explain the assertion
- A. Both Assertion & Reason are true, and the reason explains the assertion
- B. Both Assertion & Reason are true, but the reason does not explain the assertion
- C. Assertion is true, but Reason is false
- D. Both Assertion and Reason are false
Explanation
Electrons are the majority carriers in N-type semiconductors, and they are electrically neutral, but neutrality does not explain the majority carrier property.

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.
