PN Junction Diode Interview Questions and Answers: 1. What is a P-N junction? Ans. The contact surface between the layers of P-type and N-type semiconductor pieces placed together so as to form a P-N junction is…
Mass Action Law in Semiconductor: As already mentioned, concentration of free electrons and holes is always equal in an intrinsic semiconductor. When N-type impurity is added to an intrinsic semiconductor, the concentration of free electrons…
Layout of Nuclear Power Plant: The layout of nuclear power plant is shown in Fig.3.4. The main components of nuclear power plant are 1. Nuclear reactor, 2. Steam generator, 3. Turbine, 4. Coolant pump &…
Capacitance of a Single Phase Two Wire Line: Consider a Capacitance of a Single Phase Two Wire Line consisting of two parallel conductors A and B spaced d metres apart in air. Suppose that radius…
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 family. In this diode microwave…
Antenna Scanning Methods: Radar antennas are often made to scan a given area of the surrounding space, but the actual scanning pattern depends on the application. Figure 16-6 shows some typical Antenna Scanning Methods. The…
Difference between Macro shock and Micro shock: The difference between Macro shock and Micro shock is given in table below Sl no Macro Shock Micro Shock 1 A Physiological response to a current applied to…
Double Line to Ground Fault (LLG): Figure 11.9 shows a Double Line to Ground Fault at F in a power system. The fault may in general have an impedance Zf as shown. The current and…
Why we need for Power System Protection? Need for power system protection are growing fast with more generators, transformers and large network in the systems. For system operation a high degree of reliability is required.…
Thyristor Control of 3 Phase Synchronous Motor: The synchronous motor is a constant speed motor and it develÂops torque only at synchronous speed which is directly proportional to supply frequency. Therefore, variation of frequency of…
