Transformers Make Transmitting Mains Electricity More Efficient Flashcards
1
Q
When are step-up and step-down transformers used?
A
When transmitting electricity across the country
2
Q
The voltage produced by power stations is too…
A
Los to be transmitted efficiently
3
Q
The lower the voltage…
A
The higher the current for a given amount of power, and current causes wires to heat up
4
Q
What are step-up transformers used to boost?
A
The voltage before it is transmitted
5
Q
What are step-down transformers used to for?
A
At the end of the journey to reduce the voltage so it’s more useful and safer to use
