Correct answer: D. electrons have high mobility than holes and hence high mobility of energy
- A. low loss
- B. lsipationow dis
- C. capable of handling large power
- D. electrons have high mobility than holes and hence high mobility of energy
Explanation
NPN transistors are preferred to PNP transistors because electrons have higher mobility than holes in semiconductors. Therefore, NPN transistors typically have higher performance characteristics and are more efficient in many applications.Incorrect Options and Explanations: (a) low loss - This is not a specific advantage of NPN transistors compared to PNP transistors. (b) low dissipation - Dissipation characteristics depend on the specific design and operating conditions of the transistor, not whether it is NPN or PNP. (c) capable of handling large power - This is not the primary reason for preferring NPN transistors over PNP transistors. The primary factor is the higher mobility of electrons compared to holes in semiconductors.

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.
