Curious about the cost of running appliances.
I understand the basic kWh rating to get an idea
But have been playing around with a plug in small oven.
Its rated at 1300 watts, but uses 1400w according to my plug in energy monitor
It draws about 5.8 Amps
I measured the resistance between live and neutral at the plug top when cold got about 34Ω
When the oven had been in use and hot, I unplugged and measured around 200Ω
Thing is watching the current on the monitor it stayed constant at around 5.8A ,unless the oven switch off heating.
So the changing resistance measured doesn't seem to affect current flow?
Wonder why?
