Feel really stupid asking this, but hey, up til now I've been a tumble dryer virgin...
I know that with washing machines, putting a cycle on with hardly anything in it is not cost-effective, as you use the same amount of water and electricity as a full cycle would.
But does the same apply to tumble dryers? I have a vented dryer with a sensor on it that adjusts the cycle length according to how wet the stuff is. So that makes me think that if I just put in, say, a T shirt, it shouldn't take long to dry, so shouldn't be a huge waste of electricity.
Am I right? Or deluded? Thanks :)
