Question

Which of the following is true about primary batteries?

• A. It can be reused
• B. It can be recharged
• C. It cannot be reused.
• D. Until the chemical components are active, primary batteries convert electrical energy into chemical energy.

Answer 1

The correct option is C It cannot be reused.

Electrochemical cells used for conversion of chemical energy into electrical energy are called batteries.
There are two types of batteries:
1. Primary battery
2. Secondary battery

Primary battery:
Batteries where the chemical energy is converted into electrical energy as long as the chemical components are active.

Once the active chemical components are used up it becomes dead and cannot be reused again.
It cannot to recharged again for reusing.

Examples of Primary battery are Dry cell or Leclanche cell and Mercury cells.

Thus, statement (c) is correct.
