In this article, we will see Top 10 Best Medical Universities in Pakistan, as the number of Medical universities is increasing and studying at the well-known university which provides quality education is one of the key factors behind a successful professional Carrier.
An amplifier is a electronic circuit that increases the strength of a low signal and thus acts as an amplifier. We have covered transistor basics such as what is BJT transistor, Biasing of Transistor, Different Configurations of Transistor in our previous articles. Today in this article we are going to explain working of transistor as an amplifier.
A PN junction is said to be forward biased when the externally applied voltage is in such a direction that it cancels the potential barrier of a diode, hence, allowing the current flow.
In this article, we learn about Biasing of PN Junction in detail – like how to bias a PN junction Diode (Forward & Reverse bias methods), the behavior of PN junction during forward & reverse bias, how to plot the Voltage-Current characteristics, and many other essential concepts regarding a PN junction diode. So let’s begin.
Hey, Today in this article we are going to give you the 100 NTS Electrical Engineering MCQs with answers For jobs in 2019, These MCQs are taken from electrical engineering test of National Testing Service.
“Technology leads you towards the peak with perfection”
Gunn Diodes are named after a researcher J. B. Gunn from an IBM, he discovered that the materials form group (III-V) of predict table such as Gallium arsenide (GaAs), and Indium Phosphide (InP), when applied voltage increases up to the certain value the mobility of electrons in these materials decreases, thereby producing negative differential resistance region. A diode made up of these materials can generate microwaves frequencies.
This article “Interfacing of Ultrasonic Sensor with Arduino” is updated in 2019.
Well if you are an online learner and in search of the best educational websites in Pakistan then you don’t need to search further we will provide you the best websites in Pakistan. As the Internet has made our lifestyle easy and lavish by bringing each and everything to our fingertips. Web developers are working day and night to facilitate the users to get more and more specific information on each and every single topic.
In our previous discussion, we learned that a common-emitter amplifier is most widely used amplifier circuit due to the fact that it provides good current gain and voltage gain, and Common Base Amplifier is least widely used amplifier from all three types of transistor amplifier configurations.
