More R = Less Load

An ideal 1500W heater would have a resistance of 9.6 ohms. At an ideal 120VAC it will draw 12.5A. Let's say an extension cord adds 1 ohm. Now R = 10.6 ohms.
120V/10.6 = 11.3A
120*11.3 = 1356W

The extension cord changed a 1500W load to a 1356W load.


a 40ft 12ga extension cord has a total resistance of 0.12 ohms.

now resistance is 9.8 ohms, or 12.25A or 1470 watts.

not much of an effect.
