Why is Power Factor so Important?

The specifications of any electrical appliance working on AC supply, such as a refrigerator, a toaster, a fan, etc., list a minimum of three important parameters – Voltage, Wattage and PF. The voltage rating indicates the nominal operating voltage of the appliance, the wattage rating indicates the power the appliance will use when switched on. The third parameter, PF, stands for the Power Factor – usually a value between 0.6 and 1.0. All electrical appliances consume power for operating or Read more [...]

What is a capacitor used for?

Just as a bucket holds water, a capacitor holds charge. In fact, the world's first capacitor was in the shape of a jar and was aptly named the Leyden jar. However, the latest capacitors do not look anywhere close to a jar. In its simplest form, a capacitor has two conductive plates separated by a dielectric. This helps maintain an electric charge between its plates. Depending on the type, different materials are used for the dielectric, such as plastic, paper, air, tantalum, polyester, ceramic, etc. Read more [...]

How to solder like a pro

Manual soldering is a skill that gets better with practice. For those who are starting out for the first time, manual soldering can be risky, unless they take proper care and follow safety instructions. Manual soldering involves application of heat locally by a soldering iron, whose tip may reach temperatures as high as 400°C. Soldering materials are sometimes toxic, especially if using lead based solders. Some very useful information about soldering can be found here. One of the best tips to Read more [...]
