Question
Which of these is an example of primary cell?
- Alkaline batteries
- Nickel Cadmium batteries
- Lead acid batteries
- Lithium-ion batteries
Hint:
A primary cell is a battery that is intended to be used only once before being discarded, not to be electrically recharged and then used again.
The correct answer is: Alkaline batteries
Alkaline batteries are examples of primary cells.
- The primary cells don't have free or liquid electrolytes.
- They cannot be recharged or reused easily and discarded once used.
- An alkaline battery is thus an example of the primary cell.
