## Working of NPN and PNP transistor - Electronics, Physics - eSaral

Hey, do you want to learn about the Working of NPN and PNP transistor? if yes. Then you are at the right place. P-N-P Transistor: The holes of the P region (emitter) are rippled by the positive terminal of battery $\mathrm{V}_{\mathrm{EE}}$ towards the base. The potential barrier at the emitter junction is reduced as it is forward bias and hence the holes cross this junction and penetrate into the N region. This constitutes the emitter current. The width of the base region is very thin and it is...
