Find the power drawn from the electric outlet

Reference no: EM13536058

An AC adapter for a telephone answering machine uses a transformer to reduce the line voltage of 120 V to a voltage of 5.00 V. The RMS current delivered to the answering machine is 570 mA. If the primary (input) coil of the transformer has 480 turns, then how many turns are there on the secondary (output) coil?

What is the power drawn from the electric outlet, if the transformer is assumed to be ideal?

What is the power drawn by the transformer, if 19.5 percent of the input power is dissipated as heat in the coils and in the iron core of the transformer?
