The Basic Electrical sub‑category covers the most essential basic concepts of electrical engineering. Topics such as voltage, current, resistance, power, energy, AC and DC systems are explained in a beginner-friendly manner. This section serves as a starting point for beginners and students of electrical engineering.
Amana washer locking latch clicking continuously? Here’s How to Tell If It’s Normal or Not First thing you gotta figure out…is this actually a problem, or is your washer just doing what it’s supposed to do? Because on a lot of Amana top load washers, when you hit Start/Pause, the machine runs a self-test on … Read more
Maytag Centennial Washer Shift Actuator Symptoms: How to Know That’s Your Problem If your Maytag Centennial washer is acting weird between agitate and spin…or just refusing to move past a certain point in the cycle…the shift actuator’s one of the first things worth looking at. It’s a small motorized part that tells the transmission when … Read more
Grinding noise on spin…it’s one of those sounds that makes you wanna unplug the thing immediately, and honestly that instinct isn’t wrong. But before you start pricing out a whole new washer, there’s a handful of things that cause this on Roper top loaders, and most of them aren’t as expensive as you’d think. Quick … Read more
Required Regulatory Disclosures & Terms of Use. So, you open your fresh food door and get hit with warm air. Your milk smells a bit off, and the leftover chicken is sweating. But wait—you check the freezer section, and your ice cream is still rock solid. What gives? Whether you typed “samsung fridge warm but … Read more
Tap Changing Transformer is an electro-mechanical device. All the electrical equipment we use today is designed to function properly at a specific voltage level. However, the power supplied to electrical equipment can sometimes exceed or exceed its rated voltage. This can be due to a variety of factors, such as voltage drops in distribution lines … Read more
What is a Nickel–Cadmium Battery? Nickel cadmium batteries are a relatively new addition in the United States to the storage-battery family. These batteries consist of an interleaved assembly of positive and negative plates. Construction of Nickel–Cadmium Battery Cell containers are made of nickel-plated steel. Active materials, nickel hydroxide (positive) and cadmium oxide (negative), are encased … Read more
Introduction of the Edison Storage Battery. The Nickel–Iron–Alkaline battery is the result of an effort to avoid many of the disadvantages of the lead-sulfuric acid combination and is a radical departure from it in every detail of construction. The positive plate consists of hollow, perforated, sheet-steel tubes filled with alternate layers of nickel hydrate and … Read more
Introduction Cells in which electrical energy is stored in the form of chemical reactions and, through chemical reactions again, electromotive force is produced are called secondary cells. Lead-acid cells, nickel–iron cells, and nickel–cadmium cells fall under the category of secondary cells. Here, a description of secondary cells is given. Now let’s understand the lead acid … Read more
What Is a Battery? A battery is a device that converts chemical energy into electrical energy and supplies current for use.A chemical reaction occurs between the two electrodes and the electrolyte inside, producing EMF (Electromotive Force).When the battery is connected to a closed circuit, electrons begin to flow, and electric current is produced.From small watches … Read more
What is the Cooling of Transformers? Cooling of transformers is the process by which the heat generated in the transformer windings and core is safely removed to prevent overheating, insulation damage, and failure.This heat is mainly produced due to I²R losses, hysteresis losses, and eddy-current losses. Transformer Cooling Methods The main methods used to cool … Read more
