K3-01: INDUCTION IN A TRANSFORMER

Additional Info

  • ID Code: K3-01
  • Purpose: Demonstrate that a change in the primary current induces a secondary voltage.
  • Description: A simple transformer is built from two demountable coils and an iron core. The 46-turn primary coil of the transformer is connected through a variable resistor to a 1.5 volt battery, and a large galvanometer or other measuring device is connected directly across the 500-turn secondary, as shown in the circuit diagram above. The primary current in this simple transformer circuit is changed by sliding the variable resistor contact, inducing a secondary potential which is indicated by the galvanometer. Motion of the resistor slider and current in the galvanometer are correlated.
