After a decade worth of college in EE degrees, I like to dumb down the basics of electronics for mere mortals........grins.
Power =Watts.
your wall outlet is powered by 12/2 awg wire. At 120 volt potential
1200 watts, say a blow dryer, draws 10 amps, at 120 volts. yes it's math
20 amp breakers for all wall outlets, 15 amp for ceiling lights. 12/2 for walls, 14/2 awg for lower draw circuits.
another way to think about electricity is using a 55 gallon drum of water as a power source.
How far you fill it up, is the "work" potential, or voltage. This is going to drain, (electrical current) through a valve on the bottom of the tank. The restriction of this pipe and valve is RESISTANCE, or OHMS which is resistance. So you have 4 feet tall of water, pissing out a 1" pipe at the bottom, and it's turning a water wheel. That is Watts. or Work. Higher the water level, the more potential and higher output of Watts.
hope that makes sense in layman terms. grins, I'm a sparky.
