So what do washing machines use, AC or DC?

Water and some sort of cleaning chemicals dependent on personal choice.


Did you not understand the question?


Yes and my answer made as much sense as the question.


The question only had four possible answers - "AC", "DC", "both", or "neither".

Does the current flow one way or both?

I'm guessing it flows the way it wants, usually from a hight potentail differnce to a lower potential differnce.
Depending on whther you are talking about real current or conventail current.


That was the least useful answer I've ever seen.


you mean you didn't understand it. I thought you claimed to have a degree in physics yet yuo don;t know about conventail, current flow and actual flow which is in the oppersite direction.


I know all about current flow, holes in semiconductors etc. But that's irrelevant. I asked if the flow was one way or both.

Any idea where I can find out what a typical home's power factor is nowadays?

I thought you claimed you could measure it.


But how do I know I have a typical home?


How does anyone know.


My point exactly. For typical we need data on many homes.

An average is better - some people might have lots of motors and others lots of electronics. For an accurate result it would need to be measured across many houses.


and cultures.


that would be even better, but not necessary.
