Which of the following energy conversions best describes a battery-powered resistive circuit when current is flowing?

• A. Electric to thermal to chemical
• B. Chemical to thermal to electric
• C. Electric to chemical to thermal
• D. Chemical to electric to thermal

Answer: (D)

In a battery-powered resistive circuit, the primary source of energy is the chemical energy stored in the battery. When the circuit is closed and current begins to flow, this chemical energy is converted into electrical energy as the battery powers the circuit. As the electrical energy moves through the resistive components of the circuit, it encounters resistance, which leads to the conversion of some of the electrical energy into thermal energy due to Joule heating. Thus, the sequence of energy transformations occurring in this scenario begins with chemical energy from the battery being transformed into electrical energy. As this electrical energy is utilized within the resistive circuit, it is subsequently converted into thermal energy. The correct answer describes this energy conversion process accurately, illustrating how each form of energy is related in the operation of a battery-powered resistive circuit.
