LOL.... but you mixed some of the terms here and there
Current = ( is the same ) amps.... in your analogy, it is how fast the electrons are flowing in a circuit
Voltage = potential energy ... is like pressure just as you mentioned
Power = watts... is the amount of voltage ( pressure, as you mentioned ) in combination with the amperage ( current )
Hence the formula W = V x I ( I is the symbol for amps/current and sometimes E is used instead of V for the voltage symbol, P can also be used instead of W for watts )
But also as you mentioned... there is no perfect circuit so there is some loss ( released in the form of heat that was not used in the coil itself )... but I also know that you can calculate how long a battery will last but that calculation will be off slightly due to the loss found in the circuit.
I actually can estimate how long my RC batteries will last given a certain amount of load but I can only do it after a flight once I've recharged the battery... my RC charger tells me how many mAh is put back into the battery... I take that value and divide it by the number of minutes flight I had which gives me an average... I can then say how many minutes a battery of a certain size ( mAh ) will last given that I fly at the same rate ( load ).
