National Grid - Why transformers are used

This activity presents the high voltage and low voltage scenarios and guides students through calculating the wasted power in each scenario

This helps students to see the incredible value of using High Voltage in the national grid and the role of Transformers.

This is aimed as a numerical task. It’s a separate challenge to get students to articulate this, but this exercise will spell out the numbers for them.

I suggest a sentence sequencing task to help less able students to articulate a written answer to justify the role of transformers, after completing this scenario comparison
