1. INTRODUCTION A transistor is a small electronic device that can cause changes in a large electrical output signal by small changes in a small input signal.That is, a weak input signal can be amplified (made stronger) by a transistor. For example, very weak radio signals in the air can be picked up by a wire antenna and processed by transistor amplifiers until they are strong enough to be ...Transistor
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be ...Voltage regulator
A voltage regulator is a system designed to automatically maintain a constant voltage level. A voltage regulator may use a simple feed forward design or may include negative feedback.It may use an electromechanical mechanism, or electronic components.Depending on the design, it may be used to regulate one or more AC or DC voltages.. Electronic voltage regulators are found in devices such as ...Voltage Regulator 7805 | Electrical4U
All voltage sources cannot able to give fixed output due to fluctuations in the circuit. For getting constant and steady output, the voltage regulators are implemented. The integrated circuits which are used for the regulation of voltage are termed as voltage regulator ICs. Here, we can discuss the IC 7805.…Worksheets on Electrical Engineering & Electronics All ...

Electrical symbols or electronic circuits are virtually represented by circuit diagrams. There are some standard symbols to represent the components in a circuits.Remote Control Light Circuit Diagram Using 555 Timer ...
Remote Control Light Circuit Diagram Using 555 Timer Gallery of Electronic Circuits and projects, providing lot of DIY circuit diagrams, Robotics & Microcontroller Projects, Electronic development toolsZener Diode Working with Circuit Diagram and applications
Zener Diode checking. We have discussed the application of Zener diode as voltage regulator and now we will discuss the other two points. Over voltage protection is done by using Zener diodes because there is current flowing through the diode after the reverse bias voltage exceeds a certain voltage . This circuit provides safety for the equipment connected at the terminals.Mobile Battery Charger Circuit and Working Principle ...
A mobile battery charger circuit is a device that can automatically recharge a mobile phone’s battery when the power in it gets low. Nowadays mobile phones have become an integral part of everyone’s life and hence require frequent charging of battery owing to longer duration usage.What is a Transistor?
What is a Transistor? : This category explains "What is a transistor?". And this page is a description of the transistor history. The Transistor was Invented in 1948 at Bell Telephone Laboratories．This was the beginning of the transistor history. The invention of the transistor was an unprecedented development in the electronics industry.
