AC Load Line of BJT: AC Equivalent Circuits - Capacitors behave as short-circuits to ac signals, so in the ac equivalent circuit for a transistor circuit all capacitors must be replaced with short-circuits. Power supplies…
Factors Affecting Air Conditioning System: In this modern age everybody is trying to improve his surroundings in order to make living conditions more comfortable. Air conditioning is one of the important contribution in this respect.…
Double Differentiation - Derivation: Two R-C coupling networks in cascade separated by an ampliÂfier A is shown in Fig. 29.36 (a). The amplifier A is to operate as a linear amplifier and the output impedance…
Electromagnetic Spectrum: In an earth environment, electromagnetic waves propagate in ways that depend not only on their own properties but also on those of the environment itself; some of this was seen in the preceding…
Difference Between Resistance and Arc Welding: The Difference between resistance and arc welding is given in table below Particulars Resistance Welding Arc Welding Supply Usually ac only. AC or dc. Voltage Very low. The striking…
Two layer Winding of Transformer: One important and commonly used way of neatly arranging the end connection of coils in a winding is to place two coil-sides per slot. Each coil then has one coil-side…
Power Factor Improvement: The low power factor is mainly due to the fact that most of the power loads are inductive and, therefore, take lagging currents. In order for Power Factor Improvement Methods, some device…
High Frequency Power Supply Working Principle: The high frequency power supply for coreless induction furnace is usually obtained from ordinary supply system and its frequency is converted to higher value either by means of motor-generator…
Rankine Cycle (Simple Steam Power Cycle): Rankine cycle is the theoretical cycle on which the steam turbine (engine) works. Boiler Refer the process (4) to (1): Feed water is passing to the boiler. Heat is…
What is the Principle of Sweep Generator?: Principle of Sweep Generator : The amplitude of a voltage may be directly measured on a calibrated viewing screen from the length of the straight line trace it…
