Electricity and Magnetism
Used to show how transformers work.
|Set of coils||
|AC power supply|
- Connect the AC power supply to the primary coil
- Measure the o/p voltage of the secondary coil using a digital voltmeter.
- Show that the ratio between the o/p voltage to i/p voltage is the same as ratio between the turns of the secondary coil to the turns of the primary coil Ns/Np
