Problem 9: A neon sign requires 13 kV for its operation. A transformer is used to raise the voltage from the line voltage of 220 V (rms) AC to 13 kV (rms) AC. Part (a) Find the transformer s ratio of secondary to primary turns. Part (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? Δ Part (c) How much power, in watts, does the neon sign consume when it draws the maximum current the fuse allows?
