Volts, Amps, Ohms, Watts : circuit basics

Places online to read about this stuff:
Discuss basic circuit stuff: volts, amps, ohms, watts, especially the water analogy, with
volts = height of water tank [ energy / charge ] amps = water flow =[ charge / sec ] ohms = thickness of pipe (higher ohms is thinner pipe)
Write down the fundamental equations and discuss :
volts = amps * ohms ; V = I R power = volts * amps ; Watts = V I
Draw circuit diagrams and build the corresponding circuits.
Show how to hook up meters to measure volts (in parallel) and amps (in series) and what the resistance of the meter itself is in those two cases.
For Thu, get ready do similar stuff with series and parallel resistance, LEDs, potentiometer, and measuring volts and amps in various configurations.
