30 kwi 2024 · A rheostat, also known as a variable resistor, is an electrical component used to regulate the flow of current in a circuit. Unlike a fixed resistor, a rheostat allows the user to manually adjust the resistance, which in turn controls the amount of current passing through the circuit.
11 lip 2018 · You could use a rheostat. Your heater is about 1k ohm, so a 0-1K series resistance would allow you to reduce the power to 12W minimum (and 12W would be dissipated in the rheostat). Here is a typical datasheet. Note the current specification, so you'd need a 75W pot to keep the current within spec.
