These questions came up through some discussion on another technically/ scientifically unrelated news group ................... ?
1) What happens if a DC current** flows through a domestic/residence supply meter?
2) Would it be any different if the meter was the older 'spinning disc' type or the more modern 'digital' display type?
.......................................................................................................................
1) Meter might register impulses of current in one direction only? Also since current flow would be only during a half cycle only half the energy would be transferred? AC motors would not work and anything with a transformer would output a weird waveform of half voltage or less?
2) Unknown?
PS. ** Hard to understand in what context the question was based! Gather that in fact the current 'might' be a 'mixture' of domestic AC and some DC (e.g. welding, without an interposing transformer ???). So that an AC current could have a DC bias in one direction or other????? All very puzzling!
