7. Considering the idea of transformers, there are two primary types: step-up and step-down. For a step-up transformer, the primary coil induces a larger potential difference, but smaller current in the secondary coil. For a step-down transformer, the primary coil induces a smaller potential difference, but larger current in the secondary coil. In our experiment, which kind of transformer did we create? Support your answer with evidence from this experiment.
