I’m reading a book that covers the basics of electric current, resistance, and voltage. They go on to explain ohms law, which is almost the same as watts law? So it leads me to believe that they are interchangeable terms? (Which I’m assuming they aren’t)
Is it that watts are used to measure power output vs ohms are used to measure demand of power?
I’m confused. Thanks!

If you think of electricity as water through a garden hose, it actually makes it easier to understand.
Resistance, which is measured in ohms, is how thin or restrictive the hose is.
Energy, which is measured in volts, is the pressure of the water.
Current, which is measured in amps, is how fast the water is flowing.
Power, which is measured in watts, is what the water is doing at the end of the hose such as running a sprinkler, which is the mechanical result of all of the water. Power is the result of the pressure times the flow rate.
