Question

the diagram shows a simple electrical circuit.
what type of energy transformation occurs in the circuit when the switch is closed?
a) chemical to electrical to light
b) light to electrical to chemical
c) electrical to light to mechanical
d) mechanical to electrical to light

Explanation:

• A battery stores chemical energy. When the switch is closed, the chemical energy in the battery is converted into electrical energy (due to the flow of electrons in the circuit).
• This electrical energy then flows through the circuit and is used by the light - bulb. The light - bulb converts the electrical energy into light energy (and some heat energy, but the main transformation relevant to the options is electrical to light).

Answer:

A. chemical to electrical to light
