Question

Why does electricity have to be transformed?

Answer 1

due to electrons and protons .protons push electrons and the electricity is transferred

Answer 2

the electricity have to be transformed because
When electron flow is resisted, some of the energy in the electrons does not travel through all the way. Because energy is conserved, the energy that was moving the electrons forward isconverted to heat energy. It can also be converted to light energy, as in the filament in a light bulb.
