Diodes: Working, How to Use, Applications
It’s John Ambrose Fleming (1849-1945), a British engineer, who invented the first diode in 1904, in the form of an electron tube. Later, with the development of semiconductor technology, the diode became a dipole consisting of two substrates: one, rich in free electrons, and of type N, the other deficient in electrons, and of type […]

AC Ammeter Circuit for Measuring Current across 220 V Appliances
In this article I have explained how to build a simple AC ammeter circuit which can be used for checking the current consumption of household 220 V or 120 V appliances. The main reason for high monthly utility bills is the use of large electrical equipment like refrigerators, washers and dryers, dishwashers, etc. These appliances […]
Gel Cell Battery Charger Circuit [Constant Current, Constant Voltage]
In this post I have explained what are gel cell batteries and also learn how to build a specialized charger for charging a gel cell battery, with full calculations. The proposed circuit works in two modes: it starts charging a discharged gel cell battery with constant current, until the full charge voltage is reached across […]
