Model answer
What a good answer should say
- To allow for the safe distribution of high voltage electricity.
Explanation
Why this works
Transformers are important in electrical power systems because they allow for the safe distribution of high voltage electricity. By stepping up the voltage for transmission and stepping it down for use, transformers ensure that electricity can be delivered safely and efficiently.
The consequence is that this system minimizes risks associated with high voltage while maintaining effective power delivery.
