What is Voltage and Current? There are two quantities that we like to keep track of in electronic circuits : voltage and current. These are usually changing with time; otherwise nothing interesting in happening. Voltage…
What is Vacuum Diode, Construction, Working and Applications: Construction of Vacuum Diode - Vacuum diode is the simplest form of the electron tube for the production and control of free electrons. A typical vacuum diode…
What is Tristate Logic or Three State Logic Circuit? Tristate Logic or Three State Logic Circuit - In normal logic circuits there are two states of output, either low or high. But in complex digital…
What is TRIAC? | Symbolic Representation | VI Characteristics of TRIAC: What is TRIAC? - The full form of TRIAC is Triode for Alternating Current (TRIAC) or Triode for AC. It is a bilateral switch…
What is Transition Method in Electric Traction? The methods of changing-over the connections from one grouping to another are known as transition method. The change-over from full series (when the two motors are connected in…
What is Transistor Transistor Logic (TTL) Circuit? Texas instruments introduced transistor transistor logic (TTL), a widely used family of digital devices in 1964. It is fast, inexpensive and easy to use. Transistor Transistor Logic family…
What is Transistor Biasing? - Types of Biasing As already mentioned, for normal operation of a transistor emitter-base junction is always forward biased and collector-base junction is always reverse biased. For a moment if the…
What is Thyristor? - Thyristor Family and its Applications Thyristor is the general name given to a family of semiconductor devices having four layers with a control mechanism, although this term is most commonly applied…
What is Thermionic Emission? A very common method used for electron emission is by heating the metal piece to a high temperature. The process of electron emission from the surface of metal into the surrounding…
What is Thermal Runaway and Heat Sink? The maximum average power PC max which a transistor can dissipate depends upon the construction of the transistor and may lie in the range of a few milliwatts…
