Resistance Thermometer Working Principle: The resistance of a conductor changes when its temperature is changed. This property is utilized for the measurement of temperature. The Resistance Thermometer working principle is an instrument used to measure…
Properties of Fluid in Fluid Mechanics: The following properties of fluids are of general importance to the study of fluid mechanics. Mass density (ρ) Specific Volume (v) Specific weight (w) Specific gravity (S) 1. Mass…
Cramer Rule: If the network is complex, the number of equations i.e. unknowns increases. In such case, the solution of simultaneous equations can be obtained by Cramer Rule for determinants. Let us say that set…
Sequential Circuits: There are many applications in which digital outputs are required to be generated in accordance with the sequence in which the input signals are received. This requirement cannot be satisfied using a combinational…
Insulation Coordination in High Voltage: Insulation Coordination in High Voltage - Electric power supply should ensure reliability and continuity to the utility concerns. Hence, the power lines and sub-stations are to be operated and protected…
Paper Mill Process: The raw materials for Paper Mill Process undergo two processes before the paper is available: The pulp is made from the raw materials. This pulp is converted to paper in paper making…
Thermocouple Principle and Types of Thermocouple: Thermocouple Principle consists of a junction of two dissimilar wires, so chosen that a voltage is generated by heating the junction. The output of a thermocouple is delivered to…
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 star-connected secondary. Neutral point N…
Waveguide Mixers and Detectors: As we know that ordinary transistor and tube RF amplifiers eventually fail at microwave frequencies, because of greatly increased noise, compared with their low-frequency performance. Unless a receiver is to be…
Low Frequency Response of BJT Amplifier: For analysis, we will consider the loaded voltage-divider BJT bias configuration. But the results can be applied to any configuration. For the network shown in Fig. 15.14 the capacitors…
