Why Tungsten Is Not Used As A Heating Coil?

Why Tungsten Is Not Used As A Heating Coil? due to very high melting point the tungsten wire cannot used in elctric heater and another reason is that due to heating effect of current. Is tungsten good for heating element? Tungsten mesh has been in use for high-temperature furnace heating since the early 1960s. Tungsten

How Is Thermal Energy Transferred When You Cook Something?

How Is Thermal Energy Transferred When You Cook Something? Radiation heat transfer occurs when microwave (light waves) or infrared energy (heat waves) are spread into the food. As the microwaves penetrate the food, they bump into molecules of water and fat, causing them to vibrate rapidly. This vibration creates friction, which creates heat that cooks

Which Metal Is Best For Heating Element?

Which Metal Is Best For Heating Element? Nichrome What is the best heating element? Nichrome: Most resistance wire heating elements usually use nichrome 80/20 (80% Nickel, 20% Chromium) wire, ribbon, or strip. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is

What Does The Cord Of An Electric Oven Not Glow While Its Heating Element Does?

What Does The Cord Of An Electric Oven Not Glow While Its Heating Element Does? Thus, the heating element becomes hot and glows red. On the other hand, the cords are made up of good conductors like copper. They have low resistance, and do not produce much heat when same amount of current is passed
