How do you calculate potential difference from a graph?
The answer will depend on what information is plotted on the graph!
Why is the gradient on a current-potential difference graph not the resistance?
Resistance is defined by R = V/I where V is potential difference and I is current. It is not: change in pd / change in current - which would be the gradient of the curve. Thus to measure the resistance at a particular pd we simply read off the current at that pd and use the equation above. The problem stems from the way resistors are introduced before non-ohmic components, and for ohmic components it may appear that the gradient is being used for the resistance.
What does the slope of a speed-time graph represent?
The slope of a velocity-time graph represents acceleration.
How can you represent vector quantities by using graph?

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 the difference a graph and a chart?
The difference lies in the usage of the words. For example a graph is used in math, and charts are simply a way to represent different types of data.
Why do scientist use table and graph in presenting their data or experiment?
While doing the experiment we can assume many different outcomes. Like for example when you play baseball what is the guarantee that the ball wont swing to the left or the right or its trajectory wont change.Thus scientists tabulate their findings. They then graphically represent them. The graphical representation is used to derive the conclusion for the experiment. Like for example when you are trying to derive Ohm's law you first tabulate the data and then plot a graph for the data you found out. The graph can represent:-A straight line confirming that the current is directly proportional to the potential difference across the conductor.A parabola, then the current is not directly proportional. It depends as a square of the other.Thus with these examples we see the importance of tabulation and graph plotting. Now graph plotting is very useful for computer models.
What does a reaction energy diagram represent?
A graph of Potential energy Vs time The changes in energy during a reaction <APEX>

What is the significance of the area under the curve on a current v voltage graph?
This value would represent the value for Power
What statement describes the potential energy diagram of an exothermic reaction?
The difference in potential energy between the reactants and products.
What does a point represent on a graph?
A point can represent a piece of data or an (x,y) value.
Graph of resistance of filament lamp against potential difference?
It will vary from 0 to a certain value but at a slower rate.
What is the best graph to represent fractions?
the best graph to use to represent fractions is a pie graph, that is if all the fractions denominators are the same...
How can tables and graph represent relations?
Tables and graph represent relations by showing the distribution of occurrence.
