GCSE Physics - Transformer Calculations #83

The video tutorial explains how transformers change the potential difference in an electricity supply. It covers the difference between step-up and step-down transformers and introduces two key equations that relate potential difference, current, and the number of turns on the coils. The tutorial includes examples of calculating output voltage and current using these equations.

Explain the significance of the variables V, N, and I in the transformer equations.
