Insect zappers with their blue lights

Reference no: EM13651919

In some places, insect "zappers" with their blue lights, are afamiliar sight on a summer's night. These devices use a highvoltage to electrocute insects. One such device uses an ac voltageof 4320V, which is obtained froma standard 120.0V outlet by meansof a transformer. If the primary coil has 21 turns, how many turnsare in the secondary coil?
