Quizplus · Accepted Answer

Sending current through a resistor is the operation that yields the least percentage of returnable electrical energy. This is because energy is dissipated as heat in the resistor, which cannot be recovered or reused. In contrast, charging a capacitor or a storage battery allows for a higher percentage of returnable electrical energy, as the stored energy can later be discharged or used to power devices. Similarly, establishing a current through an inductor or moving a conducting rod through a magnetic field can induce electromagnetic effects that can be harnessed for various applications.
