If an engineer needs to limit how many amps come out of a wall's circuit, how is this accomplished? I know that there is nothing preventing more than 15 amps from coming through my wall other than the breaker that trips if more is passed.
From my understanding of Ohm's law, you can limit the amps on a fixed voltage by increasing resistance. In order to get a 15 amp current, for example, out of a wall, instead of a huge current (which would obviously trip the breaker), what is used?
I am a bit confused on the whole way wattage and everything works, and I appreciate any responses!
