How many turnsare in the secondary coil

Reference no: EM13648324

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 3970 V, which is obtained from a standard 120-V outlet by meansof a transformer. If the primary coil has 30 turns, how many turnsare in the secondary coil?
