insulating board so that the entire portion is approximately 4 inches long. The nichrome wire produces heat rapidly with an electric current due to the high level of electrical resistance that the twisted wire holds. This preview has intentionally blurred sections.
A heater coil is a device used to heat water or air. Typically electric, the heater coil acts like a large resistor, and as the electric current flows through it, it begins to heat up. The resistance wire used in common household toasters is the same type of wire used in a heater coil. The amount of heat produced by the heater coil is controlled by a rheostat switch. Many appliances, such as hot water heaters, electric clothes dryers and electric ovens, all use some type of heater coil to produce heat.
