In this experiment you learn how a transformer can be used to step up a voltage enough to light a bulb. See what happens when the voltage is stepped up too much!

This item teaches:

• the relationship between the potential difference across the primary and secondary coils of a transformer
• about the potential difference across the primary and secondary coils in step-up transformers
• about step-up transformers
• how an alternating current in the primary coil of a transformer can induce an alternating potential difference in the secondary coil
• about the different types of transformers that can be used for different applications
• about transformers
• about the basic structure of a transformer
