Question

Assertion (A): Secondary cells are used in inverters.

Reason (R): A primary cell can be recharged by passing current through it in the opposite direction after it has been used.

Select the most appropriate answer from the options given below:

Options

• Both A and R are true, and R is the correct explanation of A.

• Both A and R are true, and R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is true but R is false.

Explanation:

A primary cell cannot be recharged because it undergoes an irreversible chemical reaction during use. Once the active chemicals are consumed, they cannot be restored by applying external current. The internal changes make the cell permanently inactive after discharge.
