A modern house is wired for 120.0 V, and the current is limited by circuit breakers to a maximum of 290.0 A. (For the purpose of this problem, treat these as DC quantities.) a) Calculate the minimum total resistance the circuitry in the house can have at any time. b) Calculate the maximum electrical power the house can consume.
