Electricity is transferred from power stations to consumers along the __________. It is done at a high __________ to improve the efficiency of transmission.
The step up transformer increases the voltage (potential difference), which reduces __________ while providing the same amount of power.
As we know current has a heating effect, reducing the __________ reduces the __________ effect and hence reduces __________ losses in the cables.
The step down transformer decrease the __________ to a safer level and increases the __________ to provide the power.
