PLC Components: A PLC is a solid state device designed to perform logic functions previously accomplished by electro-magnetic relays. Basically, the PLC Components is an assembly of solid state digital logic decisions which provides outputs.…
Compensating Network in Op Amp: In op-amps the variations in gain and phase shift with respect to frequency are due to the internal capacitors and stray capacitances, which are due to physical characteristics of semiconductor…
Production of Chemicals by Electrolysis: There are various industrial applications of Production of Chemicals by Electrolysis such as production of caustic soda, chlorine, potassium permanganate, ammonium per sulphate, hydrogen and oxygen by electrolysis. The most…
Rectangular Waveguide Derivation: When the top and bottom walls are added to our parallel-plane waveguide, the result is the standard Rectangular Waveguide Derivation used in practice. The two new walls do not really affect any…
What is Flash Memory in Digital Electronics? Flash Memory in Digital Electronics (sometimes called "flash RAM") is a type of constantly-powered nonvolatile memory that can be erased and reprogrammed in units of memory called Blocks.…
Mutual Inductance of Coupled Circuits: Mutual Inductance of Coupled Circuits - A voltage is induced in a coil when there is a time rate of change of current through it. The inductance parameter L, is…
Rutherford Nuclear Model of Atomic Structure: In order to explain many phenomena associated with conduction in gases, metals and semiconductors and the electron emission from a metal surface, it is necessary to assume that the…
What is Diode Resistance? What is Diode Resistance? - As already discussed, a forward-biased diode conducts easily whereas a reverse-biased diode restrains the flow of current, so a diode has a low forward resistance as…
Energy Conservation Methods: Energy Conservation Methods is the cheapest new source of energy. We should resort to various conservation measures such as cogeneration (discussed earlier), and use energy efficient motors to avoid wasteful electric uses.…
Rotor Overheating Protection Diagram: Rotor Overheating Protection is provided only in case of large generators. It indicates the level of temperature and not the actual hot spot temperature. In the arrangement shown in Fig. 11.20,…
