Thevenin Equivalent Circuit: Thevenin's theorem gives us a method for simplifying a given circuit. The Thevenin Equivalent Circuit form of any complex impedance circuit consists of an equivalent voltage source VTh, and an equivalent impedance…
Thermoelectric Refrigeration System Working: Thermoelectric Refrigeration System works on the principle of Peltier effect according to which heat energy is evolved at one junction and absorbed at the other one when direct current is passed…
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…
Thermocouple Connection: One of the most commonly used methods of measurement of moderately high temperature is the thermocouple effect. When a pair of wires made up of different metals is joined together at one end,…
Thermistor Working Principle: Thermistor Working Principle - The electrical resistance of most materials changes with temperature. By selecting materials that are very temperature sensitive, devices that are useful in temperature control circuits and for temperature…
Thermistor Operation: The word thermistor is a combination of thermal and resistor. A thermistor is a resistor with definite thermal characteristics. Most thermistors have a negative temperature coefficient (NTC), but positive temperature coefficient (PTC) devices…
Thermal Resistance to Heat Flow: The Thermal Resistance to Heat Flow between two points in a medium (e.g. insulation) is equal to temperature difference between these points divided by the heat flowing between them in…
Thermal Resistance - Definition, Circuit Diagram and Equation: With power transistors, a designer often uses a heat sink to get a high power rating for the transistor. As already mentioned, the heat sink allows the…
Thermal Relay Construction and Working Principle: Thermal Relay can operate on the principle of thermal effect of electric current. It consists of bimetallic strips which are used in small sizes and are heated by heating…
Thermal Power Station | Coal Based Thermal Power Plant: The heat released during the combustion of coal, oil or gas is used in a boiler to raise steam. In India heat generation is mostly coal…
