    broadgage:

    A full wave bridge rectifier, greatly reduces noise when energised.

    Still makes a "clunk" when it is operated, but no ongoing noise, unlike contactors with AC coils that tend to produce a continual buzz.


    AAAAAANnnnnnnnnnnnnnnnnnnnnnnndddddddddd broadgage gets full marks and a bonus point for his swift response.


    Well done broadgage.


    You go onto the next round which covers the life and the mating habits of the lesser spotted Mangle Goose of the Andes.
