# Electronic – What’s the difference between NPN and PNP transistors

bjtpnptransistors

Suppose that I know how an NPN transistor works.

How different is a PNP transistor? What are the operational differences between a PNP and a NPN?

\$V_\rm{BE}\$ will be \$-0.7\,\rm{V}\$ but it's magnitude should be the same in both PNP and NPN if you use complementary parts.
