Answer / rameez rehman

It is difficult to transform direct current from one voltage
to another; hence, initially DC had to be transmitted at the
low voltage at which it was generated and used. This fact
limited its applicability: if transmission of large amounts
of electricity or transmission over long distances was
required, the cost of the conductor (copper wire) was
prohibitive. Alternating current may be generated at a low
voltage, boosted to a higher voltage by a transformer,
transmitted and converted back to a lower voltage before use.
