Give a long answer to the question given below.
i. State Ohm’s law.
ii. What physical quantity is represented by the slope of the V–I graph shown? Define this quantity and determine its value in SI units using the graph.
iii. Derive the relation between \(1\ kWh\) and \(1\ joule\).
ii. What physical quantity is represented by the slope of the V–I graph shown? Define this quantity and determine its value in SI units using the graph.
iii. Derive the relation between \(1\ kWh\) and \(1\ joule\).

i. Ohm's law states that, at a constant temperature, the steady current '\(I\)' flowing through a conductor is to the potential difference '\(V\)' between the two ends of the conductor.
Ohm's law states that .
ii. The slope of V-I graph gives the of the conductor.
From the graph, we can see that the slope of the line is equal to .
iii. 1 kWh is equal to .
