No, not that AC/DC ... what voltage is it going to be? The problem with lower-voltage wiring is simple physics. For a given power demand, P=I*V, so a lower voltage means pushing more current.

DC, on the other hand, tends to cause deeper burns and blood electrolysis. The danger of electric shock isn’t determined by voltage or current alone—it arises from the interaction of multiple ...

A nanopower voltage regulator was added to the water-meter circuit ... The quiescent current of the added DC-DC converter is decisive here. If the switching regulator consumes too much energy ...
