Additional Info

  • ID Code: K3-05
  • 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 form a transformer (using a demountable iron core). This is used to produce large secondary current. Holding two nails together tip-to-tip across the secondary produces over 100 amps in the secondary (stepped up from 4-5 amps in the primary), welding the two nails together.
