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?
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.

Yes of course you're right with regards to AC, but what plumbing system works on the basis of the water flowing opposite directions every hundredth of a second? A particularly tricky phenomenon to find an analogy for, at least from the realms of water works.

When I was 5 years old, my mother always told me that happiness was the key to life. When I went to school, they asked me what I wanted to be when I grew up. I wrote down happy. They told me I didn't understand the assignment. I told them they didn't understand life.
