What is a PNP Transistor?PNP Transistor DefinitionA PNP transistor is defined as a bipolar junction transistor with an N-type semiconductor sandwiched between two P-type semiconductors. Symbol of PNP TransistorThe symbol includes an arrow on the Emitter showing the direction of conventional current flow. Current Flow DirectionIn a PNP transistor, the current flows from the Emitter to the Collector.Working PrincipleThe positive terminal of a voltage source (VEB) is connected with Emitter (P-type)
