Causes of Low Voltage in House Wiring?

Causes of Low Voltage in House Wiring?

all lectures, ELECTRICAL
Low voltage is a basic concept that refers to lower than normal levels of electric power entering buildings. Technically, the definition of "low voltage" is the diminution of electrical current to 90 percent of its normal capacity for a minute or more. The effects of this include poor appliance performance, dim lighting and intermittent outages. Just as serious is the possibility of overheating equipment and equipment simply malfunctioning because it is not getting the power it needs. Wires The state of the wiring in an area is a common cause of voltage problems. Age and corrosion are a common cause of low voltage, as is dirty connections and poor insulation. Poor or damaged splicing work can also be a cause. In some cases, the wires used to carry electricity have…

[video width="256" height="144" mp4="http://alvanteachings.com.ng/wp-content/uploads/2019/01/How-to-use-multimeter.mp4"][/video] This tutorial will show you how to use a digital multimeter (DMM), an indispensable tool that you can use to diagnose circuits, learn about other people's electronic designs, and even test a battery. Hence the 'multi'-'meter' (multiple measurement) name. The most basic things we measure are voltage and current. A multimeter is also great for some basic sanity checks and troubleshooting. Is your circuit not working? Does the switch work? Put a meter on it! The multimeter is your first defense when troubleshooting a system. In this tutorial we will cover measuring voltage, current, resistance and continuity. Download this video and learnmore [download id="20837"] [the_ad id="5400"] [the_ad id="5348"]

What is wireless charging? How does it work?

all lectures, COMPUTER/INTERNET, ELECTRICAL
What is wireless charging? Wireless charging is the process of charging a device wirelessly without the hassle of plugging it into a power socket in the wall, a power bank or another power source. In wireless charging, the electric charge is transferred from the charging device to the device being charged without any wired connection. Both the devices must be in direct contact or within a certain range with each other for wireless charging to work. Wireless Charging Standards Two major standards for wireless power are being used in the industry: Qi and The AirFuel Alliance. While both the standards are owned by different companies, the core technology underlying them is essentially the same. Both the standards are based on Resonant inductive coupling. The basic idea behind wireless charging started…

Home Automation: What Is It and How It Works?

all lectures, ELECTRICAL
What is Home Automation? Home automation is the system that allows communication from one device to another to make certain changes or even allow control through another device. A few years back, home automation sounded like an overrated venture and cost a substantial amount of money. However, as years go by, technology has gotten more sophisticated and thus lowering the price to have your home fully automated. With an automated home, not only do you get to enjoy the comfort that can be challenged by few systems but also enjoy sophisticated levels of security and efficiency. For instance, an automated home lets you identify who is approaching your house and allows you to open and lock your door even when away from your home. With such a system, you can…
