Today we will What talk about transistor audio power amplifier , voltage amplifier , power amplifier and and some important term in power amplifier.... What is an amplifier? A amplifier is a device that amplies weak input signal into high input signal. Their are two types of amplifier: 1) voltage amplifier 2) power amplifier. What is Transistor audio power amplifier? A transistor which raises the power level of signal in audio frequency range is called Transistor audio power amplifier. What is voltage amplifier? It is used to raise the voltage level of input signal What is power amplifier? It may be defined as the device that converts Dc power into Ac power. It is used to raise the power level of input signal. Need of a power amplifier? We know that voltage level of a signal is raised by using a voltage amplifier.buy this amplified signal does not have the power required by an electronic circuit. Hence we have to raise the power level of signal . This expla...

Heys guys welcome to blog, In this blog we talk about fitness. Fitness Fitness is not only about no. of muscle mass in your body but it is the ability to perform physical activities. A fit body leads to fits mind. Fitness through exercise  Nowadays there is a trend of going gym among the students . But some of them can't go gym because of three reasons. They are:- 1) They can't manage time . 2) They can't invest money because going gym per month cost at least Rs (500 - 1000). 3) They can't buy supplements(Creatine , Bcaa , fish oil , whey protein , AHCC , casein and many others). So without gym and supplements we can't build a good physic? Umm..that's not true , we can build a good physic at home also. Some of the exercise we can do at home are:- 1) pushup/pushup variation:-  These exercise target chest , tricep and shoulder muscle.   2) pullup/weighted pull-ups:-   These exercise target lats which helps you to develop thick back. 3)squad/si...

Thermal Generation When at room temperature say 32°c some heat energy is gain by the valence electrons to break the covalent bond and become free from it parents atom,this electron is called free electron. It can move in the structure of atom randomly. It leaves a hole from where it become free by breaking the covalent bond. The process of Generation of holes-electron pair due to thermal energy is called thermal Generation.                   Recombination When a covalent bond is broken and an electron leaves from it's parents atom, it creates a holes at the place from where it become free The free electron which become free from the covalent bond moves at randomly combines with holes and the covalent bond is from again.The process of combination of holes and free electron is called recombination.                                    ...
