SCR as Half Wave Rectifier Circuit Diagram: SCRs are very useful in ac circuits where they may serve as rectifiers whose output current can be controlled by controlling the gate…
Complementary Metal Oxide Semiconductor (CMOS): With active load switching, the current drain with a low output is approximately equal to ID(sat). This may cause a problem with battery operated equipment.…
Advantages and Disadvantages of JFET: Junction field-effect transistors combine several merits of both conventional (or bipolar) transistors and vacuum tubes. Some of these advantages and disadvantages of JFET are enumerated…
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…
Measurement of Physical Quantities: Measurement of Physical Quantities is given by Displacement Measurement Strain Measurement Force Measurement Torque Measurement Pressure Measurement Temperature Measurement Water-Level Indicator Measurement and Display of Speed…
Measurement of Electrical Quantities: Measurement of electrical quantities which includes Measurement of Voltage Measurement of Current Frequency Measurement Phase-Angle Measurement Power-Factor Measurement Impedance Measurement VA Measurement Power Measurement VAR Measurement…
Circuit Breaker Analyzer: Short Circuit Generator: This is of a special design having very low reactance in order to give the maximum short-circuit output of the Circuit Breaker Analyzer. The…
Differential Relay Application: The principle of operation depends on a simple circulating current principle where the difference of the currents of the two CTs flows through the relay under normal…
