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?

Single Phase Transformer

A single-phase transformer is a type of power transformer. It is an electrical device that accepts converts the single phase alternating power into single phase alternating power. In this power conversion the voltage is stepped up or down. If the voltage is stepped up, the current will be stepped down and if the voltage is stepped down, the current will be stepped up.
