admin Electricity consumption is measured in units. One unit of electricity is equal to 1 kilowatt-hour (kWh). A kilowatt is a measure of power, and an hour is a measure of time. So, a kilowatt-hour is the amount of energy used by a 1,000-watt appliance in one hour. To calculate your electricity consumption in units, you … Read more
A star-delta motor starter is a type of motor starter that reduces the starting current of an induction motor by connecting the motor windings in a star configuration during startup. Once the motor has accelerated to a certain speed, the starter switches the motor windings to a delta configuration, which provides full voltage to the … Read more
An ideal transformer is a theoretical device that has no losses, such as copper losses, core losses, or leakage flux. It is a two-winding device that is used to transfer energy from one circuit to another. The two windings are called the primary winding and the secondary winding. The primary winding is connected to the … Read more
Dry cells are the most common type of battery used in everyday devices, such as flashlights, radios, and clocks. They are also known as zinc-carbon batteries or Leclanché cells. Dry cells are relatively inexpensive and easy to produce, which is why they are so widely used. Construction of a Dry Cell A dry cell is … Read more
Eddy current loss is a type of energy loss that occurs in electrically conductive materials when they are exposed to a changing magnetic field. The changing magnetic field induces an electromotive force (EMF) in the material, which causes a current to flow. This current flows in closed loops, and the energy it carries is dissipated … Read more
Eddy current loss is a form of energy dissipation occurring within electrically conductive materials when they are exposed to a fluctuating magnetic field. These materials exhibit the generation of circulating currents, termed “eddy currents,” which convert electromagnetic energy into heat. This phenomenon is crucial to comprehend, as it is a significant contributor to energy wastage … Read more
mAh, which stands for milliampere-hour, is a term often associated with batteries. But what exactly does it mean, and why is it important? In this article, we’ll explore the concept of mAh in batteries in simple terms, helping you grasp its significance without diving into complex technical jargon. Breaking Down mAh Let’s begin by breaking … Read more
Batteries are ubiquitous in our modern lives, powering everything from remote controls and flashlights to digital cameras and portable devices. Among the many battery types available, two of the most common and widely used are the AA (double-A) and AAA (triple-A) batteries. In this comprehensive article, we will explain about AA and AAA batteries, exploring … Read more
Batteries power our lives in countless ways, from our TV remotes to our digital cameras and everything in between. Among the various battery types available, AA and AAA batteries are two of the most commonly used. They may look similar at first glance, but they serve different purposes and have distinct characteristics. In this article, … Read more
A PPM meter, or parts per million meter, is a device or instrument used to measure the concentration of a substance in a solution or mixture. Parts per million (PPM) is a unit of measurement that expresses the ratio of the number of parts of a particular substance to one million parts of the entire … Read more
