Energy : Joule :: ?

Options

A. Axe : Grind
B. Ammeter : Current
C. Power : Ampere
D. Resistance : Ohm

Explanation

To solve the analogy "Energy : Joule :: ?," we need to identify the relationship between the first pair of words and apply that same relationship to find the missing term.

### Step-by-Step Solution:

1. **Identify the relationship in the first pair:**
- The first term is "Energy," and the second term is "Joule."
- Joule is the unit of measurement for energy.

2. **Determine what the second pair should represent:**
- We need to find a term that is to a unit of measurement as "Joule" is to "Energy."

3. **Consider the options provided:**
- Option A: Axe and Grind
- Option B: Ammeter and Current
- Option C: Power and Ampere
- Option D: Resistance and Ohm

4. **Analyze each option:**
- **Option A (Axe and Grind):** An axe is a tool used for cutting, not a unit of measurement.
- **Option B (Ammeter and Current):** An ammeter is a device used to measure current, which is a unit of measurement.
- **Option C (Power and Ampere):** Ampere is a unit of electric current, not power.
- **Option D (Resistance and Ohm):** Ohm is the unit of measurement for resistance.

5. **Select the correct option:**
- The correct analogy would be "Ammeter : Current" because an ammeter measures current just as a joule measures energy.

Thus, the answer to the analogy "Energy : Joule :: Ammeter : Current."
