Principle of Electromechanical Energy Conversion: Principle of Electromechanical Energy Conversion is a reversible process and Eqs (4.26) to (4.29) govern the production of mechanical force. In Fig. 4.4 if the armature is allowed to move…
Photon Absorption Coefficient: Photon Absorption Coefficient - When light falls on a semiconductor, the photons may be absorbed or they may propagate through the semiconductor depending on the photon energy (E) and the band gap…
Difference between Zener Breakdown and Avalanche Breakdown: The difference between Zener Breakdown and Avalanche Breakdown is given in table below Zener Breakdown Avalanche Breakdown This is observed in zener diodes having reverse voltage of less…
Biasing FET Switching Circuits: JFET Switching - A Biasing FET Switching Circuits is normally in an off state with zero drain current, or in an on state with a very small drain-source voltage. When the…
Waveguide Coupling: When waveguide pieces or components are joined together, the Waveguide Coupling is generally by means of some sort of flange. The function of such a flange is to ensure a smooth mechanical junction…
Voltage Multiplier Circuits: Cascaded Voltage Multiplier Circuits for higher voltages are cumbersome and require too many supply and isolating transformers. It is possible to generate very high d.c. voltages from single supply transformers by extending…
Virtual 8086 Mode in Microprocessor: The virtual 8086 mode is a special operating mode of the Pentium processor and it is a subset of protected mode. In this mode, two 8086 application programs can be…
Incidence Matrix (A): The incidence of elements to nodes in a connected graph is shown by the element node incidence matrix (A). Arrows indicated in the branches of a graph result in an oriented or…
IC Linear Voltage Regulators: 723 IC Regulator - The basic circuit of a 723 IC Linear Voltage Regulators in a dual-in-line package is shown in Fig. 17-20. This IC has a voltage reference source (D1),…
Cycloconverter Control of Induction Motor: Cycloconverter Control of Induction Motor allows variable frequency and variable voltage supply to be obtained from a fixed voltage and frequency ac supply. A half-wave Cycloconverter Control of Induction Motor…
