This brings up another question.
By keeping the same amount of work at the load, I need a different coil winding increasing the resistance to approximately 5042 ohms at 220V, 50hz, maintaining the 9.6 watts. But, I will still have a shift in power due to the reactance of the coil, so will the...
I am designing a coil for 120V 60hz, resistance is 1500 ohm, with 9.6 watts of input power. My question is what will happen when 220V 50hz is applied to the same coil?
