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 […]
Simple E-Bike Circuit [Electric Bike]
This E-bike or electric bike circuit I have explained below can be used as the control circuit for constructing a homemade E-bike, with the help of a permanent magnet motor DC (PMDC motor), and a Li-Ion battery. An electric bike is basically a bicycle powered through a motor and a battery, which does not require […]
How to Design Simple LED Driver Circuits
In this article I have explained how to design your own customized, simple LED driver circuits at home. We will learn how to calculate specific LED configurations for applying the LEDs with appropriate LED driver power supplies. In these driver power supplies I have explained two concepts one by using SMPS boards and the other […]
Types of Power Amplifier Classes Explained in Simple Words
In this post I am going to explain power amplifiers and their classification according to their output electrical characters and application. We will be exploring amplifier classes: A, B, AB, C, D, E, F, G, H, I, S and T briefly and yes, that’s a lot of amplifier types that are available in today’s electrical […]
