[AT] 3Ph, etc.

I don't usually get into these discussions but I do have a little background in this area.
Voltage = pressure - the correct term for voltage is electro-motive force.  It is the potential for energy.

Amps = current flow.  Current flow is dependent upon two things - voltage (potential) and resistance.

If you want to equate this to water, consider this - (voltage) / water pressure  = 1000 psi.  (amps) flow or gpm. is a function of the water pressure and the size of the discharge pipe (resistance).

A larger conductor is capable of carrying more flow but it will only carry more flow if there is sufficient pressure to create the flow.

Power is a function of potential (voltage) and flow (amps)  and equates to consumption or usage.

  Charlie,
  Think of it as water in  a pipe. you can't see it you know its there because 
  the pressure gauge says it  is.
  1. Pressure = Amps
  2. volume = volts. 

  1000 volts no amps safe  as can be
  1 volt 1000 amps your dead.

  Water
  3 in line no pressure  it won't hurt you
  1 in line 300 lbs pressure your dead again. 

  I have  always thought that this helps other to understand electricity  
  better.

  Then there is this 1 volt equals 160.000.000.000.000   electrons to pass a 
  given point.  I always wonder who counted them to make  sure.
