Pippin:
I don't think it's supposed to be pure coincidence that Muggles never
harnessed the power of electricity until the wizards had largely
removed themselves from day-to-day life. I think that the mere
presence of one or two underaged wizards in a home has little effect,
but large concentrations of spell-casting wizards probably would.
