The potential difference between two points also called

Options

A. voltage
B. work
C. electric power
D. rating

Answer

To answer the question "The potential difference between two points is also called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Potential Difference**:
- The potential difference is the difference in electric potential between two points in an electric field. It indicates how much work is needed to move a charge from one point to another.

2. **Identifying Points**:
- Let's denote the two points as A and B. The electric potential at point A is denoted as \( V_a \) and at point B as \( V_b \).

3. **Defining Potential Difference**:
- The potential difference (\( \Delta V \)) between these two points can be expressed mathematically as:
\[ \Delta V = V_a - V_b \]
- This means that the potential difference is equal to the potential at point A minus the potential at point B.

4. **Alternative Notation**:
- The potential difference can also be denoted as \( V_{AB} \), which represents the potential difference from point A to point B.

5. **Common Terminology**:
- The potential difference is commonly referred to as "voltage." Therefore, the potential difference between two points can also be called "voltage."

6. **Conclusion**:
- Thus, the potential difference between two points is also called "voltage."

### Final Answer:
The potential difference between two points is also called **voltage**.
