If I have a power cord that, by construction, acts as a reasonably valued capacitor through its length, will I suffer a great disadvantage compared to how much and how well it delivers power through?
Also, how much does skin effect come into play with AC, with a conductor whose radius doesn’t allow for skin effect at those frequencies (50 & 60 Hz)?
How much does skin effect depend on the overall ratio of radial proportion in width vs thickness, in a ribbon-like conductor made from foil with rounded edges? Is skin-effect of AC overall pretty much negligible in any shape and size conductor?
I also have a high capacitive power cord by design call the Zeus that cost about $70. The designer claims it can make my vacuum cleaner clean better with stronger power and make my dryer dry faster. I don’t know if he’s kidding or serious, but in my stereo, it does make the sound a little crude and overbearing. Not very good for sound. Very good for video though. Makes the picture brighter and more color saturation.
What is considered a moderately high capacitance for a power cord?
I don’t actually want any unnecessary capacitance, I’m hoping it turns out negligible despite being relatively high by design.
What would be considered a high capacitance for an AC cord?
I have an idea about maximizing conducting surface area with a ribbon-stuffed design that would, of course, be more capacitive. Hopefully not too much.
Then again I don’t know if ribbon-like conductors are good for AC so I might just do speaker cables with the design. What’s a (too) high capacitance for speaker cables?
@Arenith, given this thread and the ‘Air Capacitor’ one, I think you may be a strong contender for the ‘Mr Capacitance 2020’ award

Maybe some year, gotta learn what a capacitor is first.
