The joule effect is a physical law that describes the relationship between the heat generated and the current flowing through a conductor.

The temperature reached by the coil is directly proportional to the square of the current intensity (U2) and inversely proportional to the value of the resistance (R).

Application: For a given resistance coil (value in Ω), a higher temperature is reached when increasing the intensity (voltage). But if you keep the same voltage, a lower temperature will be obtained with a higher resistance value.
