What conclusion can you draw from the following observations on a resistor made of alloy manganin?
`{:("Current A","Voltage V","Current A","Voltage V"),(0.2,3.94,3.0,59.2),(0.4,7.87,4.0,78.8),(0.6,11.8,5.0,98.6),(0.8,15.7,6.0,118.5),(1.0,19.7,7.0,138.2),(2.0,39.4,8.0,158.0):}`

Explanation

To analyze the observations on a resistor made of alloy manganin, we can follow these steps:

### Step 1: Understand the Relationship
According to Ohm's Law, the relationship between voltage (V), current (I), and resistance (R) is given by the equation:
\[ V = I \times R \]
This means that for a given resistor, if we plot voltage (V) against current (I), we should get a straight line if the resistor obeys Ohm's Law.
