How hot is the water? This is the Amperage. If the water is cold, there is hardly any amperage. But if the water is hot, then the amps are high. If the water is boiling then the amperage could hurt or kill you.
I don't understand. Wouldn't the flow speed of the water be analogous to current?
Keep in mind that this is merely a quick example of electricity. Power in electrons is obviously much more detailed. I teach my apprentices this so that when they start off they can have a good visual picture to compare to in their heads.
Voltage is very much a "pressure, or to be precise; "Electromotive force".
Amperage runs through resistance. In reality the more amperage (load) on the circuit the actual, physical heat that radiates from the circuit itself.
So no..this example is an accurate, yet simple analogy.

Hardly, electricity travels at a constant speed in a circuit, changing the voltage or resistance does not change speed, merely the charge in the circuit. Current measured in amps is charge per second, so maybe it'd be best to say the current is like the litres/second coming out of the tap.
Ony if you are dealing with DC. The corkscrew sine wave of AC flows between its maximum voltage, to zero, to its NEGATIVE maximum voltage at any given time frame snap shot.
