The AC adapter for a telephone answering unit employs a transformer to decrease the line voltage of 146 V (rms) to a voltage 11.8 V. The rms current delivered to an answering system is 461 mA.
i) When the primary (input) coil in the transformer in adapter consists of 110 turns, determine how many turns are there on the secondary (output) coil?
ii) Determine the rms power delivered to the transformer? Suppose an ideal transformer.
