npn and pnp transistors

Postby saniya » Sun Oct 31, 2010 7:26 pm

Hello!

Apologies if this topic is already covered, I searched the forum and didn't find anything.
I was wondering if you could explain how npn and pnp transistors work. I know they are basically p-n junctions, but my book's explanation confused me....

A basic explanation will do.

Thanks heaps!

Have a look at the High School Physics FAQ at
