A transformer uses the 120 V rms from a wall socket (primary) to provide 9.0 V rms for a computer disc drive (secondary). If the transformer provides 500 mA to the secondary,
a. What is the current provided by the primary?
b. What is the reflected load resistance of the transformer (i.e. the effective resistance as
experienced by the voltage source)?
