yes corona is a loss of useable current that can be applied to the toriod
to produce streamers
no ... when you drop the voltage into the transformer the output current
also drops in perspective
to the ratio of the windings... e.g. 120V in = 60mA out ergo 80V in =
40ma out ( 80/120 =3/4
... 60X3/4 = 40)
# 3 ... not a good idea the voltage out ( sec side) will do damage to
the amp meter place
the amp meter on the primary side and do the division to get an idea of sec
side out amperage and
