Insect “zappers” use a high voltage to electrocute insects. One such device uses an AC voltage of 4320 V, which is obtained from a standard 120-V outlet by means of a transformer. a. If the primary coil has 21 turns, how many turns are in the secondary coil? b. What is the ratio of the current in the primary to current in the secondary? PLEASE SHOW ALL WORK!! Thank you!!
