Registers of 80386 Microprocessor: The 80386 processor has significantly extended the 8086 register set. All the registers of 80286 are existing in the 80386 processor and some new registers have been added in 80386. Generally,…
Register Architecture of 68000 Microprocessor: Fig. 11.1 illustrate the Register Architecture of 68000 Microprocessor. Data Registers: The data registers can be used to handle (8-bit) bytes, (16-bit) words, or 32-bit long words. When a data…
Regenerative Cycle - Definition, Advantages and Methods: Regenerative Cycle - Assume 1 kg of steam is expanded in the turbine. Before complete amount of steam is expanded, some amount of steam (m kg) is extracted…
Regenerative Braking: Sometimes the energy of the load may have to be fed to the supply system. A Chopper in this mode is called regenerative. The chopper working as a switch is connected across the…
Refrigeration Cycle Diagram: For lowering the temperature of a body below that of its surroundings and then maintaining its temperature at this lower level, a continuous extraction of the heat from the body is required.…
Refrigeration and Air Conditioning Interview Questions and Answers: 1. What is practical unit of refrigeration ? Define it. Ans. Tonne of refrigeration (TR) is the practical unit of refrigÂeration and is defined as the amount…
Refraction of Waves: As with light, Refraction of Waves takes place when electromagnetic waves pass from one propagating medium to a medium having a different density. This situation causes the wavefront to acquire a new…
Reflex Klystron Oscillator: It is possible to produce oscillations in a klystron device which has only one cavity, through which electrons pass twice. This is the Reflex Klystron Oscillator, which will now be described. The…
Reflection of Waves: There is much similarity between the reflection of light by a mirror and the reflection of electromagnetic waves by a conducting medium. In both instances the angle of reflection is equal to…
Reflection of Electromagnetic Waves by a Conducting Surface: In view of the way in which signals propagate in waveguides, it is now necessary to consider what happens to Reflection of Electromagnetic Waves when they encounter…
