So, what we have made is a transformer. Let’s test it out with a simple experiment.

Materials Required:


• Your transformer

• 9 Volt Battery

• Speaker


Connect your transformer as shown below. To one coil of the transformer connect the speaker. To the other coil MOMENTARILY touch the 9 volt battery (or any battery).  Do not leave the battery connected else it will drain immediately and ruin your cell or battery.

PLEASE RESPOND: Describe what happens to the speaker….and only when there is a MOMENTARY connection.
