We measured the wall outlet voltage in class as 124VAC with nothing plugged in, and 119VAC when a toaster was plugged in. The toaster resistance was measured and found to be 9.4 ohms. (a) Show the Thevenin and Norton equivalent circuits of the wall outlet; (b) Although both equivalent circuits correctly model the electrical behavior of the outlet at its output terminals, one of these models is wildly inaccurate in other regards - which one, and why
