Conductor Semiconductor and Insulator: Bonding Forces Between Atoms: Whether a material is a Conductor Semiconductor and Insulator depends largely upon what happens to the outer-shell electrons when the atoms bond themselves together to form a…
Central Air Conditioning Systems Construction and Working: The central air conditioning systems serving the needs of large building or spaces are generally called the year-round air conditioning systems. They have a cooling capacity of 25…
Doubled Tuned Coupled Circuits: Figure 10.24 shows a Doubled Tuned Coupled Circuits involving two series resonant circuits. For the circuit shown in the figure, a special case where the primary and secondary resonate at the…
Circuit Stability Precautions: Power Supply Decoupling - Feedback along supply lines is another source of op-amp circuit instability. This can be minimized by connecting 0.01 μF high-frequency capacitors from each supply terminal to ground (see…
Crystal Oscillators - Circuit, Working, Advantages and Disadvantages: In crystal oscillators, the usual electrical resonant circuit is replaced by a mechanically vibrating crystal. The crystal (usually quartz) has a high degree of stability in holding…
What is Intrinsic Semiconductor? An intrinsic semiconductor is one which is made of the semiconductor material in its extremely pure form. A semiconductor is not truly intrinsic unless its impurity content is less than one…
Stator Voltage Control of Induction Motor: By reducing Stator Voltage Control of Induction Motor, speed of a high-slip induction motor can be reduced by an amount which is sufficient for the speed control of some…
Programmable Unijunction Transistor: PUT Operation - The Programmable Unijunction Transistor (PUT) is actually an SCR-type device used to simulate a UJT. The interbase resistance (RBB) and the intrinsic standoff ratio (η) can be programmed to…
Laplace Transform of Impulse Function: The Laplace Transform of Impulse Function is a function which exists only at t = 0 and is zero, elsewhere. The impulse function is also called delta function. The unit…
Construction of Underground Cables: Fig. 11.1 shows the general Construction of Underground Cables. The various parts are : Cores or Conductors:Â A cable may have one or more than one core (conductor) depending upon the…
