1
Q
what is the national grid
A
the national grid is a giant system of cables and transformers that covers the UK and connects power stations to consumers
2
Q
what does the stepup transformer do

increases the voltage and decreases current of electricity generated in the power station. when this lower current is sent through the power cables less heat is produced therefore less electrical energy will be lost as heat
3
