A transformer connected to a 120-V (rms) ac line is to supply 12,500 V (rms) for a neon sign. To reduce shock hazard, a fuse is
to be introduced in the primary circuit; the fuse is to blow when the rms current in the secondary circuit exceeds 8.50 mA. (Here the "primary" line is the 120 V line and the "secondary" is the 12,500 V line). Part A Part A). What is the ratio of secondary to primary turns of the transformer? N2/N1 = ___________
Part B). What power must be supplied to the transformer when the rms secondary current is 8.50 mA? P=
Part C) What current rating should the fuse in the primary circuit have? I1=_____________A
