EMF Graph

Hello,

Quick question:
If you plot a graph of the following:
Y Axis = EMF / Voltmeter Reading across resistors
X = 1 / Ammeter Reading

What would the following tell you?
Gradient
Area under the graph
Line

Thanks,!

Can you draw the circuit? Is it just a bunch of resistors in series? Parallel? Different values or the same, and are they known?

Hello,

Thanks for the reply. Here it is.
The voltmeter was moved through all the resistors and sometimes also got the P.D over two resistors.
