About Faraday's Law and its consequences, judge the following items. I. Faraday's law implies a relationship between a time-varying electric field and the circulation of a magnetic field. II. The induced electromotive force E will produce a current in the sense of opposing the flux variation that produced it. III. The Direct Current motor (also called DC motor) has the same physical operating principle as the alternating current (AC) motor, namely: the torque of the magnetic field on current turns. IV. Transformers can
1 - About Faraday's Law and its consequences, judge the following items.
I. Faraday's law implies a relationship between a time-varying electric field and the circulation of a magnetic field.
II. The induced electromotive force E will produce a current in the sense of opposing the flux variation that produced it.
III. The Direct Current motor (also called DC motor) has the same physical operating principle as the alternating current (AC) motor, namely: the torque of the magnetic field on current turns.
IV. Transformers can be used in either direct current (DC) or alternating current (AC).
