MoreThe Electric Field. Also called the electrostatic field, the electric field 36 is not as commonly known per se as the magnetic field. In the same way that current is connected to the magnetic field, voltage is connected to the electric field. That leads to a good rule of thumb to remember: Current is magnetic and voltage is electric.
