Switch Representations of AND and OR These circuits are making simple logical decisions, two switches offer four combinations of OPEN and OFF, but only certain combinations cause the light to be turned on. BUF vs NOT BUF: NOT: The waveforms show delays between transitions on the inputs and corresponding responses at the outputs. The actual […]

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 […]

The way electrons move in a wire: When a potential difference is applied to a wire, an electric field is created across the wire, and electrons throughout the wire start moving due to this field. Together with the field the electron repels the nearest electron in the wire out of the way, this electron in […]
