What is the main purpose of the National Grid?
A
They carry electrical power over long distances.
B
A step-up transformer raises the potential difference so the current can be smaller for the same power.
C
For a fixed power, increasing the potential difference allows the same power to be transferred with a smaller current.
D
It transfers electrical power from power stations to consumers.
