This is the same heater I posted in another posted but I had more of a theory question so I thought I'd start another thread.
The heater is a 5kW 208-240V heater. With this heater since it has a fixed resistance wont the heater have (2) differnt power ouputs depending on voltage applied. I'm assuming the current is calculated using whatever voltage we apply.
For example for a 5kW heater at 240V using V^2/R I get 11.2ohms. However if 208V is applied then 208^2/11.2ohms = 3862W. So will applying the lesser voltage result in less of a power ouput? Or will the heater change its resistance due to heating between the two voltage values and thus always output 5kW? Is there a way to calculate this?
