Final answer:
Chemical energy is stored in the cell, or battery, and is converted to electrical energy to power the circuit. Thus, the correct answer is C) Cell.
Step-by-step explanation:
The question asks where chemical energy can be found: in the bulb, switch, cell, or circuit. Chemical energy is the potential energy stored within the bonds of chemical substances, which can be released during a chemical reaction. Batteries, or cells, store chemical energy and upon connection in a circuit, a chemical reaction inside the battery converts this stored energy to electrical energy, powering the flow of electrons through the circuit.
Therefore, the correct answer is C) Cell, as this is where chemical potential energy is stored and then converted into electrical energy through electrochemical or redox reactions. Other elements like bulbs and switches do not store chemical energy, but rather interact with the electrical energy produced by the cell.
