Question

Which of the following energy conversions take place in a torch?

• A. $Electrical\to Chemical\to Light$
• B. $Chemical\to Electrical\to Light$
• C. $Electrical\to Light\to Chemical$
• D. $Light\to Chemical\to electrical$

Answer 1

The correct option is B. $Chemical\to Electrical\to Light$

When the torch is turned on, the chemical energy stored in batteries is converted into electrical energy. The electrical energy, which is propagated in the form of an electric current through the bulb of the torch, is then transformed into light energy and the torch glows.
