There is no 'point on a graph' which represents Ohm's Law. It's the shape of the graph that determines whether Ohm's Law applies.
If a graph is drawn showing the resulting variation in current for changes in voltage then, for Ohm's Law to apply, the graph must be a straight line.
If the resulting graph is not a straight line, then Ohm's Law doesn't apply.

How do you calculate 1.67 ohms?
ohms law.
Is it true that In Ohms law the variable i represents the rate of flow of charge which is called impedance?
"I" represents the current which is the flow of electric charge. Impedance is the measure of the opposition to the flow of current at a given voltage usually in a.c. circuits.
Is ohms law heat and light?
No.
Do transformer violates ohms law?
no
Where you r not apply ohms law?
in transformer
How do you plot ohms law graph of potential difference versus current?
The current is represented by the horizontal (x) axis, and the potential difference is represented by the vertical (y) axis.If the resulting graph is a straight line, then it confirms that the circuit is obeying Ohm's Law. If the resulting graph is a curve, then the circuit does not obey Ohm's Law.The gradient at any point along of the resulting line represents the resistance of the load for that ratio of voltage to current.
What is the significance of the intercept of the graph for charles's law?
The intercept of -273¤C on the Charles law graph represents the absolute minimum of temperature below which it is not possible to go -Chukwuma Akubueze
How do you calculate 1.67 ohms?
ohms law.
Can you describe an experiment to demonstrate Ohms Law?
You need a d.c. variable-voltage supply, a voltmeter, an ammeter, and a resistive load. The voltmeter must be connected in parallel with the resistive load, and the ammeter in series.Gradually increase the voltage across the load, in discrete (uniform) steps. For each step, note the values of voltage and corresponding current.Use your results to plot a graph, with voltage along the horizontal axis, and current along the vertical axis.If the resulting graph is a straight line, then the load is 'linear' or 'ohmic', and obey's Ohm's Law. If the resulting graph is a curve, then the load is 'non-linear' or 'non-ohmic', and does NOT obey Ohm's Law.The reciprocal of the slope of the graph, at any point along its length, represents the resistance at that point. For a straight-line graph, the resistance will be constant (obeying Ohm's Law); for a curved-line graph, the resistance will vary along its length (does no obey Ohm's Law).Remember that Ohm's Law is not a universal law, in other words not all loads obey Ohm's Law - these include metals such as tungsten (used to make the filaments of incandescent lamps), electrolytes, and most solid state devices, such as diodes, etc.
What is represented by the E I and R in the formula E IR?
In the formula E=IR, E represents voltage (in volts), I represents current (in amperes), and R represents resistance (in ohms). This formula is known as Ohm's Law in electrical engineering.
Describe in your own words a graph of charles law?
A graph of Charles's Law would show a direct relationship between the volume of a gas and its temperature at constant pressure. As temperature increases, the volume of the gas also increases proportionally. This relationship is represented by a straight line passing through the origin on a graph where the x-axis represents temperature and the y-axis represents volume.
Is it true that In Ohms law the variable i represents the rate of flow of charge which is called impedance?
"I" represents the current which is the flow of electric charge. Impedance is the measure of the opposition to the flow of current at a given voltage usually in a.c. circuits.
How do you find conductance using ohms law?
To find the conductance using ohms law,you take the inverse of the resistance(/R)
