Higher resistance hotter
Web19 de jan. de 2024 · When cold, they have 3x-5x higher resistance. When powered on, they heat up to like 400K and their resistance gets at minimum (rated power). When … WebAs Ohm’s equation suggests, coils with a higher ohm (high resistance) require less wattage and current. Conclusion Ohm’s power triangle states that when you keep voltage constant and lower the resistance, you increase the current in an electrical device.
