Is electricty matter

Answer 1

Yes. Electricity is a charge, i.e. an imbalance in the number of electrons between two points. Electrons have mass and mass is matter. Also, voltage is energy per charge, in joules per coulomb. Energy is also mass, by Einstein's mass-energy equivalence equation e = mc2. So, you have electricity as charge representing electrons, which have mass, and you also have electric potential as energy representing mass.
