1. An electronic device for repelling fish with Lorenzini organs, comprising:
a generator having a power supply and output terminals including a first output terminal and a second output terminal, for converting a DC voltage supplied from the power supply to an AC voltage having an amplitude of less than 100V and outputting the AC voltage from the output terminals;
wherein the generator further comprises:
a storage that stores a plurality of patterns of AC voltage, which is output from the output terminals, having different waveforms; and
a selecting switch for selecting one of the plurality of patterns of AC voltage stored in the storage;
at least one electric wire, one or each of which is connected to one or both of the first output terminal and the second output terminal; and,
a power switch that forms an electric circuit together with the generator and the at least one electric wire to turn on and off the output from the power supply, and that causes the power supply to supply a DC voltage when the first output terminal and the second output terminal are electrically connected via the seawater;
wherein
the power switch has an electrical current sensor, and is configured to supply a DC voltage from the power supply when the electrical current sensor detects an electrical current flowing between the first output terminal and the second output terminal; and
the selecting switch selects one of the plurality of patterns of AC voltage stored in the storage according to the magnitude of the electrical current detected by the electrical current sensor.
