Which cell converts electrical energy into chemical energy ?

Options

A. Dry cell
B. Electrolytic cell
C. Electrochemical cell
D. None of these

Answer

To determine which cell converts electrical energy into chemical energy, we can analyze the characteristics and functions of different types of electrochemical cells.

### Step-by-Step Solution:

1. **Understanding Electrochemical Cells**: Electrochemical cells are devices that convert chemical energy into electrical energy and vice versa. There are two main types: galvanic (or voltaic) cells and electrolytic cells.

2. **Galvanic Cells**: These cells convert chemical energy into electrical energy through spontaneous redox reactions. In a galvanic cell, the chemical reaction occurs naturally, producing electrical energy that can be harnessed to do work.

3. **Electrolytic Cells**: Unlike galvanic cells, electrolytic cells require an external source of electrical energy to drive a non-spontaneous chemical reaction. In this case, electrical energy is used to cause a chemical change, effectively converting electrical energy into chemical energy.

4. **Conclusion**: Based on the definitions and functions of the two types of cells, it is clear that the cell that converts electrical energy into chemical energy is the **electrolytic cell**.

### Final Answer:
The cell that converts electrical energy into chemical energy is an **electrolytic cell**.
