Problem: A 580.9-W space heater is designed for operation in Germany, where household electrical outlets supply 230 V (rms) service.
Part A: What is the power output of the heater when plugged into a 120-V (rms) electrical outlet in a house in the United States?
I need help to solve the above question and ignore the effects of temperature on the heater's resistance.
