Question

Quizplus · Accepted Answer

According to the law of conservation of energy, the output power of an ideal transformer should be equal to the input power. Therefore, the best choice is option B, which states that the output power is equal to the input power. Option A and Option C are incorrect, as an ideal transformer does not create or destroy energy, so the output power cannot be greater or smaller than the input power. Option D is incorrect, as only one of the choices is correct.
