Black holes

Black Holes What is a black hole? A black hole is a region of spacetime from which nothing can escape, even light. To see why this happens, imagine throwing a tennis ball into the air. The harder you throw the tennis ball, the faster it is travelling when it leaves your hand and the higher […]

BLACK HOLES

STAR A star is a luminous globe of gas producing its own heat and light by nuclear reactions (nuclear fusion). They are born from nebulae and consist mostly of hydrogen and helium gas. Surface temperatures range from 2000C to above 30,000C, and the corresponding colours from red to blue-white. The brightest stars have masses 100 […]

BIG-BANG THEORY

Big Bang Theory The Big Bang theory occurred several years back. The formation of big bang theory resulted in the formation of our universe. The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our […]

ATOM

ATOM The atom is a basic unit of matter consisting of a dense, central nucleus surrounded by a cloud of negatively charged electrons. The atomic nucleus contains a mix of positively charged protons and electrically neutral neutrons (except in the case of Hydrogen-1, which is the only stable nuclide with no neutron). The electrons of […]

ANALOG ELECTRONICS

Transistor: It is a solid state device, whose operation depends upon the flow of electric charge carriers within the solid. It is capable of amplification. Transistor Terminals: It consists of three parts:- 1) Emitter: It is left hand section of the transistor and its main function is to supply majority charge carriers. It is always […]

AMPLIFIER

1.Introduction to Amplifiers In “Electronics“, signal amplifiers are widely used devices as they have the ability to amplify a relatively small input voltage signal, for example from a Sensor or microphone, into a much larger output signal to drive a Relay, lamp or loudspeaker for example. There are many forms of amplifiers, from Operational Amplifiers […]

Amorphous Semiconductor Thin Film And it’s Application

INTRODUCTION:- 1950s, Stanford Ovshinsky created an entirely new realm of materials science, which in turn has given new life to the engineering of semiconductors, solar energy, and electric cars. Amorphous materials are of interest because of their complexity and unique structural and electronic properties. While crystalline and amorphous silicon are widely used in the manufacture […]

AC MOTOR AND GENERATOR

ALTERNATING CURRENT (AC) & DIRECT CURRENT(DC) o Direct current, which is electricity flowing in a constant direction, and/or possessing a voltage with constant polarity. DC is the kind of electricity made by a battery (with definite positive and negative terminals), or the kind of charge generated by rubbing certain types of materials against each other. […]

Stepper motor application

Stepper motors were developed in the early 1960’s as a low cost alternative to position servo systems in the emerging computer peripheral industry. A stepper motor is a brushless, synchronous electric motor that can divide a full rotation into a large number of steps. The motor’s position can be controlled precisely, without any feedback mechanism. […]
