BeBOP Chapter 4 Key Note: Semiconductors
The Electromechanical Relay Vacuum Tubes Semiconductors Semiconductor Diodes Bipolar Junction Transistors (BJTs) NPN: When the P-type silicon is in the middle, a positive potential difference has to be applied to the base to let it conduct, otherwise it will not conduct. PNP: When the N-type silicon is in the middle, a negative potential difference has […]
