DEM49 Transformer Kit

Objective:

– To demonstrate the effects of changing the ‘turns ratio’ between primary and secondary windings of a transformer.

Apparatus:

  • OHP voltmeter, AC
  • Model transformer (EM12)
  • 400 winding inductor
  • 1600 winding inductor
  • Power supply (S4-C)

DEM49 - Transformer Kit

Method:

Assemble all components on the OHP, except the power supply. Apply about 4 V AC and measure primary and secondary voltages with the OHP meter. Proceed as in DEM49A, method I, then reverse the primary/secondary connections and re-measure the voltages.
