PNP TransistorsA PNP transistor is comprised of two large pieces of P-Type material with a very small piece of N-Typematerial sandwiched in-between. The small piece of N-Type material is the base of the transistor. It caneither connect the two outer pieces of P-Type material together or not. The base voltage level controls the transistor and allows current between the collector and the emitter. If adecreasing voltage level is placed on the base of the transistor that is lower than the voltage on the emitter,the transistor's barrier voltage will be reached. When the barrier voltage is reached there will be
