Question

Which of the following energy conversions takes place in a torch?
A) Electrical -> chemical -> light
B) chemical -> Electrical -> light
C) Electrical -> light -> chemical
D) light -> chemical -> Electrical

Answer 1

Hint
A battery is formed using the chemical and when the chemical reaction occurs it leads to the formation of electric current which is responsible for producing light.

Complete step-by-step answer:
As we all know that the, an industrial society works of its ability to convert energy formed from one form with the another form
The energy contained in the rushing water, burning, converted into electricity is then stored in chemical batteries for releases in a host of other applications. When you flick the switch on you flashlight you are taking part in the energy conversion
When we talk about the batteries,
Batteries are formed using chemicals, and when these chemicals react with each other it leads to the movement of the electron, Due to movement of the electron electricity runs through out the circuit and hence light glows
So the correct answer is given by the option number (2)
Chemical -> Electrical -> light

Note
A battery is a device consisting of one and more electrochemical cells with external connection for powering the electrical device such as flash light, mobile player and electrical cars.
When a battery is supplying electric power, its positive terminal is the cathode and its negative terminal is the anode.
