Does PNP transistor share the same formulas as an NPN transistor?

[Femme_physics]

The formulas in question are:

Beta = Ic/Ib
Ie = Ib ( 1 + beta )
Ie = Ib + Ic

Yes, of course. Though the polarity is reversed. The terminals are named such that those equations are obeyed for both pnp and npn transistors.

Ahh...got it, so really the only difference is that +Vbe in NPN becomes +Veb in PNP

Thanks

You could ask yourself why the equations shouldn't apply. If you can't come up with a good reason then they would apply.

Thanks for the validation :)
