A cell is used to:

Options

A. measure current in a circuit
B. provide current in a circuit
C. limit current in a circuit
D. prevent current in a circuit

Answer

**Step-by-Step Solution:**

1. **Understanding the Definition of a Cell:**
A cell is a basic unit of a battery that converts chemical energy into electrical energy. It is essential in electrical circuits as it provides the necessary voltage to drive the current.

2. **Types of Cells:**
- **Primary Cells:** These are non-rechargeable cells that generate electricity through chemical reactions. Once the chemicals are used up, the cell cannot be reused.
- **Secondary Cells (Rechargeable Batteries):** These cells can be recharged and reused multiple times. They convert electrical energy back into chemical energy during charging.

3. **Function of a Cell in a Circuit:**
The primary function of a cell in an electrical circuit is to provide a constant flow of electric current. This is essential for powering devices and components within the circuit.

4. **Applications of Cells:**
Cells are used in various applications, from small devices like remote controls and watches to larger applications like electric vehicles and renewable energy storage systems.

5. **Conclusion:**
In summary, a cell is used to generate and provide electrical current in a circuit, enabling the operation of various electrical devices.
