Transistor Terminals (Emitter, Collector and Base): As mentioned already, transistor is a single crystal in which there are two P-N junctions, as shown in Fig. 10.1. The idea behind is…
Three Phase Rectifiers: Three-Phase Half-Wave Rectifier : Figure 9.11 illustrates a circuit for a 3-phase half-wave rectifier. The three diodes are connected to the three phases of a 3-phase transformer…
What is Bleeder Resistor? - Working and Its Functions The operation of an inductor filter is based on the fact that a minimum current flows through it at all times.…
What is Surge Current? - Definition and Workings Before switching on of power supply, the filter capacitor is uncharged [Fig. 9.23]. At the instant the power supply is switched on,…
Baritt diode - Working and Applications: The barrier-inject transit time (BARITT) diode is basically a back-to-back pair of diodes biased into reach-through condition. It belongs to the transit-time microwave diode…
Varistors or Voltage Dependent Resistors (VDRS): Varistors, also called the voltage dependent resistors (VDRs), show a high degree of nonlinearity between their resistance value and the applied voltage. They are…
What is Schottky Diode? - Definition, Symbols and Construction: At lower frequencies, an ordinary diode can easily turn off when the bias changes from forward to reverse. But with the…
Tunnel Diode Construction and Working: Tunnel Diode Construction and Working - The tunnel diode (sometimes called the Esaki diode after its inventor, Dr. Leo Esaki) is a high conductivity, heavily…
