Electric-field strength is defined as the ratio of the force on a positive test charge at rest to the magnitude of the test charge in the limit as the magnitude of the test charge approaches zero. The units of electric-field strength are volts per meter (V m−1). Electric charges and currents are sources of electric and magnetic fields, and Maxwell’s equations [1] provide the mathematical relationships between electromagnetic (EM) fields and sources.
