Hi,
I would like to fit up a small filament lamp as an indicator
to a water heating element, to show when the element is on.
The heating element takes roughly 10 Amperes, the lamp could
be any of those little 2 watt bulbs.
I was thinking of a 24v 50mA type, i have a few of them.
I was thinking of trying to use a small audio transformer
salvaged from an old transistor radio, i was just going to
work by trial and error, till i got it right ...
Unless someone could give me some guidance on it ?
The primary would simply be the wire that feeds the element.
Its unlikely to need two turns, but i don't know yet.
Cheers, John
