Which of the following represents voltage?

Options

A. `"Work done"/("current" xx "Time")`
B. `"Work done" xx "Charge"`
C. `("Work done" xx "Time")/"Current"`
D. `("Work done" xx "Charge")/"Time"`

Explanation

To determine which of the given options represents voltage, we can analyze the relationship between work done, charge, and voltage.

### Step-by-Step Solution:

1. **Understand the Definition of Voltage**:
Voltage, also known as electric potential difference, is defined as the work done per unit charge to move a charge between two points in an electric field.

2. **Use the Formula for Voltage**:
The formula for voltage (V) can be expressed as:
\[ V = \frac{W}{Q} \]
where:
- \( V \) = Voltage
- \( W \) = Work done
- \( Q \) = Charge

3. **Relate Charge to Current and Time**:
We know that charge (Q) can be expressed in terms of current (I) and time (t):
\[ Q = I \times t \]
where:
- \( I \) = Current
- \( t \) = Time

4. **Substitute Charge in the Voltage Formula**:
By substituting \( Q \) in the voltage formula, we get:
\[ V = \frac{W}{I \times t} \]

5. **Rearranging the Formula**:
Rearranging the equation gives us:
\[ V = \frac{W}{I \cdot t} \]
This shows that voltage is directly related to work done and inversely related to the product of current and time.

6. **Conclusion**:
Therefore, voltage can be represented as the work done per unit of charge, or in terms of current and time as shown above.

### Final Answer:
The correct representation of voltage is given by the formula \( V = \frac{W}{I \cdot t} \).
