The different models of PTC thermistors from EPCOS are equally diverse, offering the matching PTC, positive temperature coefficient, is a term used to describe the resistance characteristics of ceramic thermistor heating elements and . Again, the PTC has self-protecting properties (increased resistance in case of a circuit malfunction), Figure 2Inrush current limiting in an industrial inverter. They are electrically insulated to maintain safety and prevent electrolysis of the liquid that is being heated. But one, the resistor, seems to limit the current in the circuit The high-density heating of the disc is conducted through the extrusion to a larger area of the surface. Thermistors are more accurate than standard resistors because they only measure specific ranges of heat or cool, making them more precise than general resistors. If being able to adjust the temperature is more important than holding a fixed temperature, then a PTC material whose resistance changes smoothly with temperature can be used. while the other, the heating element, draws more current and converts it to heat. A heating element is a resistor tuned to produce as much heat as possible when current is passing through . The immersion heaters are also referred to as conductive heaters.

Since the resistance goes up pretty quickly I have no doubt to be able to control that. An induction motor is simple in structure, is robust, and its speed depends on the frequency of the power supply. You cannot use "standard" PWM with a relay to run a heating element since the relay cannot respond to high frequency signals. @jameslarge but if that was true, wouldn't it cause batteries to lose the same amount of energy and discharge at the same rate regardless of the resistance in the circuit ? The major difference in characteristics between a resistor and a heating element is that resistors are designed from a material standpoint to have a low thermal resistance change.
