Atransformer connected to a 120 v (rms) ac line is to supply 13,000 v (rms) for a neon sign. to reduce shock hazard, a fuse is to be inserted in the primary circuit; the fuse is to blow when the rms current in the secondary circuit exceeds 8.50 ma.
(a) what is theratio of secondary to primary turns of the transformer?
(b) whatpower must be supplied to the transformer when the rms secondarycurrent is 8.50 ma?
(c) what current rating should the fuse in theprimary circuit have?
