    摘要: A heater is provided with a bulb, a first heating element which has a negative temperature coefficient of resistance and a first rated heating power and forms a first coil in the bulb, a second heating element which has a positive temperature coefficient of resistance and a second rated heating power that is lower than the first rated heating power and is disposed in the bulb. The second heating element is placed adjacent to the first heating to heat the first heating element at an initial stage of a power supplying to the heater, thereby reducing resistance of the first heating element.
