What is lathe machine and its types? – What is CNC lathe machine?

Lathe machine is a type of machine tool or it can be said that it is a production machine tool. It is Use to remove metals from the work piece through lathe machine. So that the work piece can get a desired shape or size. Removal of metal from the work piece is called secondary … Read more

What are the types of transistor oscillators? – Types of transistor oscillator

In the previous article we got some information about oscillators definition, sinusoidal oscillators, essential of transistor oscillators, so today we are going to discuss the different types of transistor oscillators. So let’s start the topic. If the tank and feedback circuit are properly connected a transistor can work as an oscillator to produce continuous discontinuous … Read more

Sinusoidal oscillator – What is Barkhausen criterion – Essentials of transistor oscillator

Before knowing about sinusoidal oscillator, we will get some information about oscillator. After that we will learn about Positive Feedback Amplifier, Essential of Transistor Oscillator and Barkhausen Criterion. So let’s start the topic. Oscillator definition An oscillator is an electronic circuit that produces a repeating electronic signal in equal intervals of time. They are widely … Read more

What is meant by atomic physics? – Importance of atomic physics.

What is meant by nuclear physics? So let us tell you that under atomic physics, atoms are studied as separate bodies of electrons and atomic nuclei. Nuclear physics is the scientific study of the structure of the atom, its energy state, and its interactions with other particles and with electric and magnetic fields. In this, … Read more

What are the different classification of power amplifiers?

A transistor power amplifiers handles large signals. Many of those inputs are driven so hard by the large signal that the collector current either cut-off or is in the saturation region during a large portion of the input cycle. Therefore, such amplifiers are generally classified according to their mode of operation, that is the part … Read more

What is transistor audio power amplifier?

Definition – A transistor amplifier which amplifies the power level of a signal having audio frequency range is known as transistor audio power amplifier. A practical amplifier always consists of several stages that amplify a weak signal until sufficient power is available to operate a loudspeaker or other output device. In this multistage amplifier the … Read more

What are special purpose diodes – Zener diode

The most common use of diodes is rectification. Rectifier diodes are use in power supplies to convert a. c. voltage to d. c. voltage. But the diode can’t do only rectification.  Now a days in this fast developing world many specific types of diodes are manufactured for specific application. So some special purpose diodes are … Read more
