Why do we need transformers on the electrical grid? (Two of these options are correct)
To step up the voltage and lower the current which reduces heat loss over long distances
To step down the voltage and increase the current which reduces heat loss over long distances
To step down the voltage and increase the current which makes the electrical power safer for use in the community
To step up the voltage and decrease the current which makes the electrical power safer for use in the community
