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!

Ohm is resistance. A thin wire has a lot of Ohms, wich means applying a given voltage only very little current will flow. Ohm is how hard it is to make current flow.
Watt is power (energy per second), so voltage times current. While Ohm depends on the device Watt depends on how your operate it. Watt is how much work is being done at the moment.
In some cases they can be related. For a constant current the energy loss in Watt is proportional to the resistance in Ohm (P=I²*R). That is the kind of Watt you want to avoid though.
