Question

Complete the correlation:

Resistance: The ohm :: Potential difference :​

Answer 1

volts

Explanation:

Potential difference is a measure of the difference in energy between two parts of a circuit. The bigger the difference in energy, the bigger the potential difference. Potential difference is measured in volts . The symbol for volts is V.

Answer 2

The completed correlation will be, Resistance: The ohm :: Potential difference : Volt

To understand the correlation, we have to know more about units.

Units :

• "Unit is basically quantity of a constant magnitude which is used as a reference for measuring magnitudes of other quantities having the identical nature."
• There are different unit systems also, like - SI system, CGS system etc.
• Eg. SI unit of length is meter, SI unit of force is Newton, etc.

Similarly, the given correlation is also based upon the relationship between a physical quantity and its SI unit.

First term = Resistance

Second term = Ohm = SI unit of the first term

So,

Third term = Potential difference

Fourth term = SI unit of second term = Volt

(As, volt is the SI unit of potential difference)

Hence, we can come to a conclusion, that the "Volt" will complete the given correlation, by maintaining the same kind of relationship between the first term and second term of the correlation.
