Can someoe explain why so many different types of systems and the advantages/disatvantages of each?
Just be glad there is no color on there for DC.
From personal experience (and ohms law) I know that 220-240V requires less amps (thus resulting in smaller wire) compared to 110-120V to push the same wattage.
I also learned from experience with VFD's that 50HZ makes a 60HZ motor sound slow and 60HZ makes a 50HZ motor sound like it's in overdrive.
I've been told that if you were shocked 50hz it's less likely to cause ventricular fibrillation than 60hz because the 60hz is closer to your actual heart rate. Has anyone else heard this before?
That's the first time I've ever heard that
I wouldn't think that 3600 or 3000 cycles per minute make that much of a difference when comparing it to 60 to 120 bpm.
