Pnp schematic

WebA PNP works in a same but opposite fashion. The base still controls current flow, but that current flows in the opposite direction -- from emitter to collector. Instead of electrons, the emitter emits "holes" (a conceptual absence of electrons) which are collected by the collector. The transistor is kind of like an electron valve. http://learningaboutelectronics.com/Articles/How-to-connect-a-pnp-transistor-in-a-circuit.php

WebPNP Transistor Switching Circuit . The equations for calculating the Base resistance, Collector current and voltages are exactly the same as for the previous NPN transistor switch. The difference this time is that we are switching power with a PNP transistor (sourcing current) instead of switching ground with an NPN transistor (sinking current pokemon cards in the world https://numbermoja.com
