We are sometimes exposed to electric fields. To determine if there is a risk of overload, there is a rule of thumb that prevents sparks from switching if there is a field strength greater than 1kV per mm, ie 1MV / m. a) How big is the electrical field most between two conductors in a 230V wire (the peak voltage...
