Explain how electricity is generated and distributed, and why it is so useful and powerful for modern society.

Generation transmission---distribution

Explanation:

Electricity is generated from the generating station which could be (thermal, hydro, nuclear, coal etc) ,it is generated at a low voltage and is being step up to a higher voltage with the aid of transformers. This transformers step up and step down voltages from one level to another. At the transmission end they ensure the voltage get to the distribution end .the distribution end ensures the voltages are being supplied to nearby homes. The rated voltage for homes is 230v in some countries or 110V in other countries.

Electricity is useful and powerful for modern society because majority of the equipments in use today depends on electricity for use.which makes it very important.
