✦ Synopsis

UNEXPLORED FIELDS IN ELECTRICAL EIgGIIffEERI.'qG. 559 ground, and the conductor, which is less positive towards the ground, will be negative towards the conductor, which is more positive towards the ground. But with regard to each other, of each pair of conductors, one is negative with regards to the other, and the other positive with regard to the former. You may, for instance, consider an insulated circuit, energized by a direct current source. One of its terminals is positive, the other negative, with regard to the other. If now you connect the circuit to the positive terminal o{ a high voltage source, of which you ground the other terminal, the entire circuit will be positive towards the ground, but still the one circuit terminal is negative regarding to the other, and the current flows in the eircnit exactly as before That is, positive and negative are relative terms only, but not absolute, in their electrical engineering meaning.
