Feb 14, 2018 · These AC circuits series has taken us on a journey which has seen us discuss what AC really is all about, how its generated, some histories, concepts behind AC, its waveform, characteristics and some properties.Today we will be going over some terms and quantities associated with the Alternating Current.

Aug 15, 2017 · Stepper motors are increasingly taking its position in the world of the electronics. Starting from a normal Surveillance camera to a complicated CNC machines/Robot these stepper motors are used everywhere as actuators since they provide accurate controlling. A Stepper Motor is a brushless, synchronous motor which completes a full rotation into a number of steps.

Jul 12, 2023 · In the realm of digital electronics and logic circuits, the NAND gates stands as a fundamental cornerstone that wields immense power in information processing. NAND, short for Negated AND, is a logical operation that produces an output of low only when all of its inputs are high.. In this article, we will go over how to build a NAND gate circuit with transistors.

May 9, 2022 · In this article we will be learning about the features and working of a 4s 40A Battery Management System (BMS) which is commonly used with 18650 Li-ion cells,we will look at all the components and the circuitry of the module. I have done complete reverse engineering of this module to find out how it works so that I can show how the BMS works.
