Question

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

• A. $\text{Light}\to \text{Chemical}\to \text{Electrical}$
• B. $\text{Electrical}\to \text{Light}\to \text{Chemical}$
• C. $\text{Chemical}\to \text{Electrical}\to \text{Light}$
• D. $\text{Electrical}\to \text{Chemical}\to \text{Light}$

Answer 1

The correct option is C $\text{Chemical}\to \text{Electrical}\to \text{Light}$

When the torch is turned ON, the circuit closes. The chemical energy stored in cells is converted into electrical energy. The electrical energy, which flows through the bulb of the torch is then transformed into light energy and the torch bulb glows.
