Champion Generator not even close to rated output

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.

That all works out, but I am still puzzled.

I think the loaded voltage would go down by adding the extension cord, and that if loaded voltage goes down that means you have more load. I must not be looking at it right.
