So lets use the water as an example of the flow of electricity(voltage and/or amps).And the faucet's valve that controls the flow is the speakers ohms(resistance). A speaker at 1 ohm would represent the water faucet being opened or turn up at the maxium or high level which a large amount of water would be flowing.The large amount of water would also represent the amount of power/wattage.Now a speaker that is 8 ohms would represent the valve turned down to a minimum level creating a smaller flow of water or "power" flowing
anything else just ask

This again is false.
Resistance is a DC measurement weighted in Ohms. Resistance is a constant, just like DC power.
Impedance is an AC measurement weighted also in Ohms. What makes impedance different is that like AC current it is variable.
A speaker has an Ohm rated Impedance as the rating is variable.
What you call a 4 Ohm speaker is a speaker with an average Ohm of 4. DC resistance on a 4 Ohm speaker at rest is usually around 3.6 Ohm DC.
The water analogy only works in terms of amplifier output. A 16 Ohm speaker will sound the same as a 1 Ohm speaker providing they are powered the same at respective amp output.
