WebBipolar transistors are constructed of a three-layer semiconductor “sandwich” either PNP or NPN. As such, transistors register as two diodes connected back-to-back when tested with a multimeter’s “resistance” or “diode check” function as illustrated in the figure below. Low resistance readings on the base with the black negative (-) leads correspond to an N-type … WebPNP Transistor. The PNP Transistor is the exact opposite to the NPN Transistor device we looked at in the previous tutorial. Basically, in this type of PNP transistor construction, the …
