What is Rectifier? A rectifier is a device that simply converts alternating current (AC) into direct current (DC). The way a rectifier changes AC to DC is by the use...
Ethernet Bus: This is a coax based Ethernet network where all machines are daisy chained using RG58 coaxial cable (sometime referred to as Thin Ethernet or Thin-net). Machine 2 wants...
What is optocoupler? An optocoupler is an optical link and it connects two circuits via this link. The optical link is contained within a chip. A Light Emitting Diode inside...
The below Figure illustrates the basic operation of a BJT as a switching device. In part (a), the transistor is in the cutoff region because the base-emitter junction is not forward-biased....
Token Ring At the start, a free Token is circulating on the ring, this is a data frame which to all intents and purposes is an empty vessel for transporting...
Animated diagram showing the operation of a tuned circuit (LC circuit). This is an improvement over previous versions of this animation which uses variable frame display times to show...
The bridge rectifier uses four diodes connected as shown in Figure. When the input cycle is positive as in part (a), diodes D1 and D2 are forward-biased and conduct current in the...
