Question

A transformer connected to a 120V .C A source (effective value) must provide
13,000 V (effective value) for a noon ad. To prevent the risk of shock, a
fuse is inserted into the primary circuit; the fuse must fuse if the effective current
exceed the value of 8.50 mA in secondary. (a) What is the ratio between the number of spirals and the number of secondary turns of this transformer? (b) What is the power supplied to the transformer when the effective current in the secondary is 8.50 mA? (c) What should be the maximum current of the fuse inserted in the primary circuit?
