Transformers and the national grid

A very comprehensive worksheet about transformers and the national grid that gives students some raw data about transmitting electricity at different voltages so they can gain insight into why this is done so they’re more likely to remember. Similarly, it gives them raw data about the voltage, current and number of turns on the primary and secondary coils so they can identify the relationships themselves. There are some worked examples of using the transformer equation and then lots of practice questions.
