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!

The Ohm is a measure of resistance. Watts are volts * amps, which is roughly the speed times the volume of current at a point. Watts are a measure of work done.
[edit] and looking at the relationship another way, resistance refers to the amount of work (watts) needed to induce an electric current. But the ohm scale does not map to volt amps (watts) as it refers to the object doing the conducting, not the object inducing the current/doing the work.
