What exactly is 'voltage gradient' all about? Are there some exacting parameters in the physics dept that would lend definition to this?
Is this an established bond or connection made to equalize potential from internal or external influence?
Or should i ask is it to isolate from, or gain a common denominator to all?
Can an area or group of conductables that are connected in some manner have a different 'gradient' than a similar scenario next door?
Does this 'gradient' need to be established by man made means, or can it occur naturally?
