Simple Designing 12V 5A Linear Power Supply
This is a 12V 5A linear power supply circuit. Also, how to find resistors onside. I like to use a series of 78xx regulator ICs. Because it is so easy with a few parts. If we want 12V output. So, use 7812. But Maximum current at the output does not exceed 1A. What can we … Read more
Resistor Color Codes and How to Read Them
A resistor is the most common and useful component in electronics, so let’s learn more about them. For instance, getting to know the resistor color code, learning how to read them, and knowing some standard resistor values will make using them much easier. We use resistors in almost every electronic circuit, and they are also … Read more
