- 13- 3. Shastri recalled reading that for an ideal transformer, "the ratio of the primary voltage to the secondary voltage is equal to the ratio of the secondary current to the primary current." Plan and design an experiment to investigate whether the statement above is true. (8) • With the aid of a fully labelled circuit diagram, describe a procedure which can be used to investigate whether the statement is true. The circuit diagram must include the following components: A variable AC voltage supply • AC voltmeters • AC ammeters A transformer with adjustable turns ratio Connecting wires • ° A load resistor
