Hint: From the given question we have to learn about the ohm's law and ohm's law verified by the graph between potential difference and current conductor, and we have to prove law experimentally also. First of all let’s discuss Ohm's law.
Complete step-by-step solution:
Ohm's law states that the electric current is directly proportional to voltage and inversely proportional to the resistance of the two points. Ohm's law is, $
V = IR \\
I = \dfrac{V}{R} \\
$
Where V is the voltage,
I is the current,
R is resistance.
Physical condition is the necessary condition for the ohms law whereas the temperature of the conductor remains the same.
Graph procedure,
From the graph we concluded between the potential difference and current and the straight line is passing through the origin of the graph as shown in the above graph. In the above graph potential difference is (V) and current is (I) or (A).
Physical quantity obtained in the graph is resistance.
Ohms law can be verified by noting the values of current and voltage through ammeter and voltmeter readings.
Note: Straight line in the graph shows that the current is directly proportional to the potential difference. Ohm's law is used to verify the resistance, current, and voltmeter. The graph gives the resistance at a certain point of the given temperature. From the given question, we have proved all the given information. Physical quantity used in V-I graph is resistance.
