Which of the transistors p-n-p and n-p-n is more useful and why ? |
| Answer» Solution :n-p-n transistor is more useful than p-n-p transistor. In n-p-n transistor, electrons are the main charge carriers while in p-n-p transistor, holes are the main charge carriers. But electrons have-higher mobility than holes, so n-p-n TRANSISTORS are more COMMONLY USED than p-n-p transistors. | |
