set of 3 coils-one main primary coil
240V, 2400 turns and two
interchangeable secondary coils 65
turns and 130 turns, each giving output
of about 6V and 12V respectively at a
maximum current rating of 2A, with
number of turns and current/voltage
rating marked on each coil.
a metal ring frame of dia 12cm,
carrying an insulating bush with a
circular metal disc electrode on upper
side. A light weight metal strip is
pivoted at the center of ring to provide
deflection with charging of electrode.
