1.	Out of the transistors n-p-n and p-n-p which one is more commonly used and why?
Answer» n-p-n transistor is more commonly used than p-n-p transistor. Because in n-p-n transistor electrons are the main charge carriers while in p-n-p transistor holes are the main charge carriers. The mobility of electrons is much higher than those of holes.
