A
The power generation station, the cables and transformers
2
Q
What does the national grid do?
A
Distributes electricity around the country
3
Q
What do step up transformers do?
A
Step up the voltage and therefore decrease the current
4
Q
What do step down transformers do?
A
Step down voltage and therefore increase the current
5
Q
What do transformers do overall?
A
Reduces heat loss in the cables and increases efficiency
6
Q
What is the advantage of using thicker wires?
A
Increases efficiency as thicker wires have a lower electrical resistance
