What is described as a device that converts chemical energy to electric energy?A batteryB capacitorC lightbulbD resistor

Step 1: Break Down the Problem

To answer this question, we need to identify the role of each device listed in converting energy types. The options are:

1. Battery
2. Capacitor
3. Lightbulb
4. Resistor

Step 2: Relevant Concepts

• Battery: A device that stores chemical energy and converts it to electrical energy through electrochemical reactions.
• Capacitor: Stores electrical energy in an electric field but does not convert chemical energy.
• Lightbulb: Converts electrical energy to light energy.
• Resistor: A component that resists the flow of electric current, converting electrical energy to heat energy.

Step 3: Analysis and Detail

• The battery uses chemical reactions to create a flow of electrons (electricity), making it the only device that converts chemical energy to electrical energy among the options provided.
• The capacitor and resistor do not involve chemical energy conversion.
• The lightbulb again does not deal with chemical energy as it is solely concerned with converting electrical energy to light.

Step 4: Verify and Summarize

Among the four options, the battery is the only device that meets the described function of converting chemical energy to electric energy accurately.

Final Answer

The correct answer is A) battery.
