g The function of those little black transformers that clog your power strips is to step down line voltage to run small electronic gadgets. Suppose a fax machine uses an ideal transformer with a primary voltage of 120 V and 300 primary windings. If the secondary voltage is 12 V, find A) the number of turns on the secondary. B) If the fax machine at idle draws enough current to dissipate 6 W, find the current that must flow in the primary g
