Answer:
Fire was one of humankind's earliest and greatest discoveries—something like one or two million years ago. In our modern age of jet engines, space rockets, steel skyscrapers, and synthetic plastics, smoke and flames might seem positively prehistoric. But all four of those inventions—and dozens of others besides—rely on fire in one crucial way or another.
Fire is nothing less than brilliant, but it's not all that convenient. Sometimes it takes ages to get a fire going: coal-powered steam locomotives have to be fired up several hours before they need to pull trains, for example. Other times fire breaks out when you least expect it, threatening lives, buildings, and everything you hold dear. Wouldn't it be great if fire were as easy to control as electricity, so you could switch it on and off at a moment's notice? That's the basic idea behind heating elements. They're the "fire" inside such things as electric heaters, showers, toasters, stoves, hair dryers, clothes dryers, soldering irons and all kinds of other handy household appliances. Heating elements give us the power of fire with the convenience of electricity. Let's take a closer look at what they are and how they work!
