Series Capacitor - Working Principle, Phasor diaagram, Application: In EHV and UHV transmission lines, series capacitor are connected in series with the line to reduce the effect of inductive reactance XL between the sending end…
Leakage Current in a Transistor and Breakdown Voltage: Leakage Currents: In CB circuits shown in Fig. 10.77, if emitter current is made zero, the B-C junction still remains reverse biased and therefore, a reverse-bias leakage…
Three Modes of Heat Transfer (Conduction, Convection, Radiation): A heated substance will give off heat to another substance at a lower temperature. The three different modes of heat transfer are Conduction, Convection and Radiation. 1.…
Voltage and Current in Series Resonant Circuit: The variation of impedance and current with frequency of Voltage and Current in Series Resonant Circuit is shown in Fig. 8.7. At resonant frequency, the capacitive reactance is…
Power Supply for Electrolytic Process: Power Supply for Electrolytic Process is direct current and at very low voltage. The power required for electrodeposition is usually very small (between 100 and 200 amperes at 10 or…
Methods of Determining Depreciation: There is reduction in the value of the equipment and other property of the plant every year due to depreciation. Therefore, a suitable amount (known as depreciation charge) must be set…
Emitter Follower at High Frequencies: Emitter Follower at High Frequencies circuit is given in Fig. 19.48(a). A capacitance CL is included across the load because the emitter follower is often used to drive capacitive loads.…
Ideal Voltage Transfer Curve of Op Amp: Ideal Voltage Transfer Curve of Op Amp - The ideal op-amp produces the output proportional to the difference between the two input voltages. The graphical representation of this…
Autotransformer | Definition | Use of Auto transformer: So far two-winding transformers have been discussed wherein the windings are electrically isolated. When the primary and secondary windings are electrically connected so that a part of…
Frequency Stability of Oscillator: An oscillator having initially been set at a particular frequency does not maintain its initial frequency, but instead drift and wander about in frequency, sometimes uniformly in one direction, sometimes quite…
