If you enjoyed this explanation then don't forget to share it with your friends. So, that's all from this blog, I hope you get the idea about the Working of NPN and PNP transistor. The holes of the P region (emitter) are rippled by the positive terminal of battery $\mathrm$ Comparison table between CB, CE and CC configuration Hey, do you want to learn about the Working of NPN and PNP transistor? if yes.

And as you decrease voltage to the base of a NPN transistor, the transistor turns on less and less, until the voltage is so low, the transistor no longer conducts across emitter to collector, and shuts off.

When you increase voltage to the base of a NPN transistor, the transistor is turned on more and more until it conducts fully from emitter to collector.

A NPN transistor conducts from emitter to collector.

And as you decrease voltage to the base of a PNP transistor, the transistor turns on more and more, until the transistor fully conducts from collector to emitter.

When you increase voltage to the base of a PNP transistor, the transistor is turned off more and more until it no longer conducts and completely shuts off.A PNP transistor conducts from collector to emitter.The difference between a PNP transistor and a NPN transistor is their polarity and their actions are reversed… PNP Transistor (you should see my project after reading this post) I’ve decided to write this post to support a bit of the theory behind my new project that identifies the PNP and NPN transistors easily.
