Question

An ideal transformer is plugged into a 12-V, 60-Hz ac outlet in a motor home, thus enabling the owners to use a 1500-W, 120-V hair dryer. (Ignore any inductance or capacitance associated with the hair dryer.)
(a) What type of transformer should be used and what should its turn ratio be? When the hair dryer is in operation,
(b) What is its resistance?
(c) What are its frequency, rms voltage, and rms current?
(d) What are its peak current and peak voltage and peak power output?
(e) What are the peak power, current, and voltage values on the input side of the transformer?
