Final answer:
In a battery-powered resistive circuit, the energy conversion sequence when current flows is from chemical to electric to thermal energy.
Step-by-step explanation:
The energy conversions that take place in a battery-powered resistive circuit when the current is flowing can be best described as Chemical to electric to thermal. Initially, the battery uses the chemical potential energy stored in it and converts it to electrical energy which powers the electrons to move through the circuit. As electrons flow through the resistive elements of the circuit, like the resistors and lightbulbs, the electrical energy is then converted into heat and, in some cases, light energy as well. This sequence of energy conversions reflects the conservation of energy principle within the circuit.
