Question

Which of the following is the advantage of an accumulator over a dry cell?

• A. An accumulator is leak proof.
• B. An accumulator is cheap.
• C. An accumulator is rechargeable.
• D. An accumulator is portable.

Answer 1

The correct option is C An accumulator is rechargeable.

In the dry cell, once the chemicals have been consumed, further reaction is not possible. In an accumulator, original reactants are regenerated by passing direct current from external source. Thus, an accumulator is a secondary cell and can be recharged while a dry cell is a primary cell that is not rechargeable.
