Understanding Chemical to Electrical Energy Transformation
The question asks to identify the equipment that converts chemical energy into electrical energy. Let's analyze the function of each option:
- Electric Motor: This device converts electrical energy into mechanical energy.
- Battery: A battery stores chemical energy and converts it into electrical energy through electrochemical reactions.
- Candle: Burning a candle converts stored chemical energy into heat and light energy.
- Photo cell (Solar Cell): This device converts light energy (radiant energy) into electrical energy.
Based on this analysis, the equipment that transforms chemical energy into electrical energy is the battery.
Correct Equipment Identification
The transformation process required is Chemical Energy $\rightarrow$ Electrical Energy.
Comparing this to the functions of the options provided:
- Electric Motor: Electrical $\rightarrow$ Mechanical
- Battery: Chemical $\rightarrow$ Electrical
- Candle: Chemical $\rightarrow$ Heat + Light
- Photo cell: Light $\rightarrow$ Electrical
Therefore, the correct option is the Battery.
