Re: Electricity as Water
From: "Frank I. Reiter" <FIR at istar_ca>
I have never figured out a simple way to represent watts in the
"Electricity
as water" metaphor. The product of pressure and volume is probably
proportional to ability to drive a turbine, which would relate it to
total
energy (watts), but few listeners have real world experience of that to
relate to.
Frank.
Frank try replacing "volume" with a rate of water flow (ie current) and
it works very well.
Current has the same meaning for both electrons or molecules of water.
A quantity of something moved at a particular rate.
In fact you could say that a pump requires a certain amount of power or
watts to pump water through a given circuit at a given rate even if the
pump was turned by hand.
