A demonstration transformer is a laboratory apparatus used to demonstrate the principles of electromagnetic induction and transformers. It typically consists of two coils of wire wound around a common iron core, with the number of turns on one coil being different from the number of turns on the other.
When an alternating current (AC) is passed through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil. The voltage induced in the secondary coil is proportional to the ratio of the number of turns in the secondary coil to the number of turns in the primary coil, and the current is inversely proportional to that ratio.
Demonstration transformers are used in laboratory settings to demonstrate and teach the principles of electromagnetic induction and transformers, and to show the effects of changing the number of turns in the coils or the frequency of the AC.
