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.

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.
