So why is it some things are so simple to understand when you read about it in a book... then when you attempt to apply them they become so difficult?
I have a circuit with a 12V power source. A 1KOhm Pot and a Fan. I'm trying to calculate the max wattage I would need the resistor to handle as to not overheat in the circuit.
The fan is rated as 12V .35A. I'm afraid I don't have enough knowledge to understand how to calculate the wattage across the resistor in this circuit. I would think the wattage would be greatest when the Pot is set at the full 1Kohm? So I've tried several calculation base on 1Kohm, but nothing seems to come out correctly.
Thanks for any tips/pointers on getting this one figured out.
