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.
This is what is known as a convection current. Itâs what happens when you heat a pot of water on the stove or turn on a convection heater in a cold room. Because air is a poor heat conductor, convection heaters work slowly, gradually warming the air until itâs reached a uniform temperature.

Each works on the same principle, but generates and distributes heat in different ways.
