The surface electric field E and Maxwell current density JM have been measured simultaneously under and near small Florida thunderstorms. These records show that the amplitude of JM is of the order of 1 nA/m2 or less in the absence of precipitation and that there are regular time variations ...

The meaning of ELECTRIC CURRENT is a movement of positive or negative electric particles (such as electrons) accompanied by such observable effects as the production of heat, of a magnetic field, or of chemical transformations.
Electric current definition and calculations. Electric current definition Electrical current is the flow rate ofelectric chargein electric field, usually in electrical circuit. Using water pipe analogy, we can visualize the electrical current as water current that flows in a pipe. ...

For this external electric field exposure of 10 kV/m, local induced current densities as high as 20 mA/m2 are found in the head and trunk with even higher values (above 150 mA/m2) in the legs. These currents are considerably higher than the 4 or even 10 mA/m2 that have been ...
