1 volt equals

Options

A. 1 joule
B. 1 jule per coulomb
C. 1 coulomb per metre
D. 1 newton per coulomb

Explanation

To solve the question "1 volt equals," we will analyze the definition of a volt and the options provided.

### Step-by-Step Solution:

1. **Understand the Definition of a Volt**:
- A volt (V) is defined as the potential difference that will move one joule (J) of energy per one coulomb (C) of electric charge.

2. **Write the Formula**:
- From the definition, we can express this relationship mathematically as:
\[ 1 \text{ Volt} = \frac{1 \text{ Joule}}{1 \text{ Coulomb}} \]

3. **Analyze the Options**:
- Now, let's look at the options provided:
- Option 1: 1 Joule
- Option 2: 1 Joule per Coulomb
- Option 3: 1 Coulomb per Meter
- Option 4: 1 Newton per Coulomb

4. **Identify the Correct Option**:
- From our formula, we see that 1 volt is equal to 1 joule per coulomb. Therefore, the correct answer is:
\[ \text{Option 2: } 1 \text{ Joule per Coulomb} \]

5. **Conclusion**:
- Thus, we conclude that:
\[ 1 \text{ Volt} = 1 \text{ Joule per Coulomb} \]
