I read about bridge rectifiers yesterday... It is needed for AC to DC conversion. 4 diodes are required.
What do voltage and current have to do with a zappicator?
The zappicator is not the same as the zapper. I do not use zappers any more, I use Rife technology and frequency generators, which is much more effective.
The zappicator is a magnetic treatment of food and water... There is no current going from the zappicator.
