Maximum Power Transfer Theorem: Here, the maximum power transfer theorem has been discussed for resistive loads. The maximum power transfer theorem states that the maximum power is delivered from a source to its load when…
Differential Voltmeter: The Differential Voltmeter technique, is one of the most common and accurate methods of measuring unknown voltages. In this technique, the voltmeter is used to indicate the difference between known and unknown voltages,…
Derivation of Single Phase Quantity from Three Phase System: It will be seen later that auxiliary channels or pilot wires are used to transmit information from one end of the line to the other end.…
8086 Interrupt Types: The 8086 Interrupt Types are Dedicated Interrupts: Type 0 : Divide by Zero Interrupt When the quotient from either a DIV or IDIV instruction is too large to fit in the result register;…
Photodetectors - Definition and Applications: Photodetectors are the semiconductor devices that can detect optical signals through electronic processes. The extension of coherent and incoherent light sources into the far-infrared region on one hand and the…
Transfer Function of Armature Controlled DC Motor: The speed of a dc motor can be controlled by varying the voltage applied to the armature of a dc motor. A separately excited dc motor with variable…
Waste Heat Recovery System: Waste heat recovery system is the heat which is not at all used and exhausted out as a waste product. Waste heat is normally available from the industry in the form…
Continuous Balance DVM: Continuous Balance DVM - The basic block diagram of a servo balancing potentiometer type DVM is shown in Fig. 5.15. The input voltage is applied to one side of a mechanical chopper…
Reversible Drives using Phase Controlled Converters: When speed control in both forward and reverse directions is required a Reversible Drives is used. In several applications the speed reversal may be required very frequently in which…
Single Line to Ground Fault: Figure 11.4 shows a Single Line to Ground Fault at F in a power system through a fault impedance Zf. The phases are so labelled that the fault occurs on…
