An AC adapter for a telephone-answering unit uses atransformer to reduce the line voltage of 120 V (rms) to a voltageof 8.5 V. The rms current delivered tothe answering system is 410 mA.

(a) If the primary (input) coil in thetransformer in the adapter has 240 turns, how many turns are thereon the secondary (output) coil?

turns

(b) What is the rms power delivered to the transformer? Assume anideal transformer.
