Circuit Breaker vs Fuse, Which One is Safer and Reliable?

160 Views

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

7805 Pin Configuration and Voltage Regulator Circuit

3411 Views

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

32734 Views

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

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

11232 Views

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
