Select the term that relates to the third term in the same way that the second term relates to the first term.
Ammeter : Current :: Ohmmeter : ?

Options

A. Pressure
B. Resistance
C. Speed
D. Voltage

Answer

To solve the analogy problem, we need to understand the relationship between the first pair of terms and then apply that same relationship to the second pair.

1. **Identify the relationship in the first pair:**
- The first term is "Ammeter" and the second term is "Current."
- An ammeter is an instrument used to measure electric current.

2. **Determine the corresponding term for the second pair:**
- The third term is "Ohmmeter."
- An ohmmeter is an instrument used to measure resistance.

3. **Establish the relationship:**
- Just as an ammeter measures current, an ohmmeter measures resistance.

4. **Conclusion:**
- Therefore, the term that relates to "Ohmmeter" in the same way that "Current" relates to "Ammeter" is "Resistance."

The final answer is: **Resistance.**
