Serial Communication Interface 8251: Most of the microprocessors are designed for parallel communication. In parallel communication number of lines required to transfer data depend on the number of bits to be transferred. For example, to…
Current and Voltage Connection in Distance Relay: It is essential for the distance relay to measure the same distance between the fault and the relay under any type of fault condition. It is possible to…
Types of Travelling Wave Tubes: The TWT is the most versatile and most frequently used microwave tube. Four Types of Travelling Wave Tubes, each with particular applications and performance requirements. These are now described. TWT…
Frame Leakage Protection of Busbar or Fault Bus Protection: Frame Leakage Protection of Busbar or Fault Bus Protection is one of the most simple form of protection and is applicable to small size metal-clad switchgear.…
Phase Control of Three Phase Induction Motor: Figure 11.44 shows the schematic representation of Phase Control of Three Phase Induction Motor. Two thyristors are connected in antiparallel in each line. The firing sequence of the…
Monostable Multivibrator - Operation, Types and Application: Monostable multivibrator is a two-stage amplifier with two states—one stable state and another quasi-stable state. The circuit has two transistors Q1 and Q2, one being in the offstate,…
68000 Stack and Queue: 68000 Stack and Queue - 68000 supports stack and queue data structures with the address register indirect position direct and predecrement addressing modes. A stack operates on the principle of Last…
Diffraction of radio waves: Diffraction of radio waves is yet another property shared with optics and concerns itself with the behaviour of electromagnetic waves, as affected by the presence of small slits in a conducting…
Determination of the Synchronous Reactance | Open Circuit and Short Circuit test of Synchronous Machine: Determination of the Synchronous Reactance - With the assumption of a linear magnetic circuit, the circuit model (per phase) of…
Space Charge Region at a Junction: As explained already, the interface separating the N and P-regions is called the metallurgical junction. Let us consider a step junction in which the doping concentration is uniform in…
