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".


I don't know of any washing machine that plugs into a DC supply.


The motor silly.

They may exist I don;t know and care about as much.
Older washing machines were usually run by women turning handles and rubbing clothes on rocks or wash boards.


Were they naked?

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


Work it out yourself.


Not possible without dismantling the machine.

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.


So go find it.


Google failed me.

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.


It would be necessary for a meaningful result.


No, only for a very meaningful result.
