... An isolating transformer has THE SAME number of turns on the primary and secondary coil. The mains supply is hidden in an isolating transformer. The output terminals are NOT live so there is no danger of you getting electrocuted if you touch them with wet hands. An ordinary circuit is not used becau ...
