Webheat to be conducted. Thermal resistance is represented as the quotient of the temperature difference between two given points by the heat flow between the two points (amount of heat flow per unit time). This means that the higher the thermal resistance, the more difficult it is for heat to be conducted, and vice versa. Web16 de ago. de 2024 · But rather than switching from copper cables to iron ones in order to increase resistance of the whole circuit, you use the power switch at your heater to increase the resistance of the heater alone. So you still get (almost) twice the resistance and less power dissipated. You pay smaller power bill, but your room is colder now.
