Question: 1 / 400

How does chemical energy convert in a circuit?

It transforms into thermal energy only.

It is solely converted to light energy.

It becomes electrical energy and may produce light and heat energy.

In a circuit, chemical energy is typically stored in the batteries or electrochemical cells. As the circuit is completed, this chemical energy undergoes a transformation into electrical energy. This conversion allows electrons to flow through the circuit, facilitating the operation of various components.

In many circuits, especially those that include light bulbs or resistors, the electrical energy can then be further transformed into light energy, as seen in incandescent bulbs or LEDs, and thermal energy, which is often the result of resistance in the wires or other components. Therefore, the ability of chemical energy to convert into electrical energy and generate light and heat energy is a fundamental part of how circuits function. This multifaceted nature of energy conversion is why the selected answer accurately captures the essence of energy transformation within a circuit.
