(a) Find the transformer's ratio of secondary to primary turns. (b) If the fuse in the transformer's primary winding blows at 0.65 A (rms), what is the maximum rms current, in milliamperes, that the neon sign can draw, assuming no power loss in the transformer? (c) How much power, in watts, does the neon sign consume when it draws the maximum current the fuse allows?

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.
