DEM49 - Transformer Kit

Objective:

- To demonstrate the effects of changing the 'turns ratio' between primary and secondary windings of a transformer.

Apparatus:


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.
