EMR only differs by frequency and polarization. The higher the frequency the
more energy. the division of EMR into bands such as radio and gamma are arbitrary.
The high frequencies can ionize atoms and are biologically dangerous for that reason.
Electricity is conducted by means of electrons in a solid conductor and positive ions
in an electrolyte. Both do this because the have two characteristics, electric charge
and a magnetic field. It is these two characteristics responsible for the transfer of
all electric power. Of course electric power can move through space. It only depends
space just like light which is EMR. October 1 2015, 9:19 am EDT
