LM317 Pinout and Basic Circuit Diagram

Aug 24, 2019

By: Genius
LM317 is a famous linear voltage regulator IC. It provides very stable, uniform and smooth output which does not fluctuate with load changes. It can also be used as a precise current limiting device which is essential for testing electronic equipment. Unlike 78xx series, the output voltage of LM317 can be adjusted using a variable resistor or a set of fixed... Read More
Circuit Breaker vs Fuse, Which One is Safer and Reliable?

Jun 10, 2019

By: Genius
Circuit breakers have made our lives easier by eliminating the need to physically replace the fuse after every short circuit or overload incident. This certainly is an advantage but if you are thinking that you won’t miss the good old fuse then you are certainly wrong.
Despite of all the advantages circuit breakers have, they still are not capable en... Read More

In this tutorial I am going to teach you about resistors, their usage and functionality, types of resistors and how to read their color code. In addition to that I am also going to show you a very basic and simple circuit to practically explain resistor’s functionality. I am writing this article for beginners and those who are new into electronics. If you ... Read More
7805 Pin Configuration and Voltage Regulator Circuit

Jun 12, 2019

By: Genius
7805 is an easy to use voltage regulator IC which outputs 5 volts rated at 1A max. It takes an unregulated DC voltage input which can be fluctuating within its input limits and converts this fluctuating voltage input into a perfectly regulated 5 volts power output. For example, a 12 volt lead acid battery when fully charged gives out approximately 12.70 volt... Read More
7812 Pin and Circuit Diagram

Dec 19, 2010

By: Genius
7812 is a famous IC which is being widely used in 12V voltage regulator circuits. Truly speaking it is a complete standalone voltage regulator. We only need to use two capacitors, one on the input and second one on the output of 7812 in order to achieve clean voltage output and even these capacitors are optional to use. To achieve 12V 1A current, 7812 should... Read More
Voltage Regulator Circuit

Nov 27, 2009

By: Genius
Voltage regulation means to prevent the voltage from dropping down or rising above a specific value. A 12 volt regulator circuit will provide exactly 12V under load as well as without load. On the other hand, an un-regulated 12V power supply output voltage with drop under while the load will increase and will rise when not under load. For example, an un-regu... Read More
7809 Pin and Circuit Diagram

Nov 04, 2009

By: Genius
7809 is a voltage regulator integrated circuit(IC) which is widely used in electronic circuits. Voltage regulator circuit can be manually built using parts available in the market but it will take a lot of time to assemble those parts on a PCB. Secondly, the cost of those parts is almost equal to the price of 7809 itself so professionals usually prefer to us... Read More
How to purchase a Solar Panel?

May 31, 2019

By: Genius
Solar panel is a power source just like a battery or an electric generator except that it generates energy only when exposed to sunlight. Solar panels are capable of generating electricity without polluting our environment therefore in my opinion solar energy is probably the most earth friendly power source that exists today. If you are reading this article ... Read More
Inverter Circuit Diagram

Apr 24, 2019

By: Genius
Power inverter is a very useful device which can convert Low voltage from a DC sources to high voltage AC. The most common power inverter is 12V to 240V inverter. Perhaps that is because 12V batteries are common and easily available. This type of power inverter usually draws high current from a DC battery therefore your battery should be able to provide a hi... Read More
