Question
Which of the following batteries is an example of a primary cell?Group of answer choicesNickel-cadmium (NiCd) also known as "nicad"Nickel-metal hydride (NiMH)AlkalineLead acid
Solution
The example of a primary cell among the given options is Alkaline.
Here's why:
-
A primary cell is a battery that is designed to be used once and discarded, and not recharged with electricity and reused like a secondary cell (or rechargeable battery).
-
Nickel-cadmium (NiCd) and Nickel-metal hydride (NiMH) batteries are both types of rechargeable batteries, which means they are secondary cells, not primary.
-
Lead acid batteries are also rechargeable, making them secondary cells as well.
-
Alkaline batteries, on the other hand, are not designed to be recharged. Once the chemical reactions that provide power are complete, the battery is depleted and should be discarded. This makes them primary cells.
