In an electrical cell while in use, the change in energy is from :
- Electrical to magnetic
- Chemical to electrical
- Mechanical to electrical
- Chemical to heat
Answer
Chemical to electrical
Reason — The electric cell maintains a constant difference in potential between the two conductors in the electrolyte by a chemical reaction to obtain a continuous flow of charge between them so a cell stores the chemical energy and it can be used as a source of current and hence chemical energy changes into electrical energy when the cell is in use.
