Purpose: Show that very large currents can be produced in the secondary of a step-down transformer.
Description: A 500-turn primary coil operated at 140 VAC and 5-turn secondary coil are used to produce large secondary current. Holding two nails together across the secondary produces over 100 amps in the secondary (4-5 amps in the primary), welding the two nails together.
