What Does the Slope Represent in a Voltage vs. Distance Graph?

Click For Summary
SUMMARY

The discussion centers on the interpretation of the slope in a Voltage vs. Distance graph derived from an electric field lab involving parallel plates. The equation obtained from the graph is y = 85x, where the slope of 85 represents the electric field strength. This is confirmed by the relationship between voltage (V) and distance (d), where the slope (V/d) directly correlates to the electric field strength (E) for parallel plates, defined as E = V/r.

PREREQUISITES
  • Understanding of electric fields and potential differences
  • Familiarity with linear graph equations
  • Knowledge of parallel plate capacitor principles
  • Basic skills in data collection and graphing
NEXT STEPS

Well I have this lab on electric field lab and what I did was measure the voltage from different distances on a parallel plate. So when I plotted the graph Voltae vs. Distance, I got a linear line and the equation was y = 85x (somewhat like that disregarding the y-intercept). My concern is what does the constant/slope represent? I'm really stumpped. Thanks

2. y = 85x



3. I think it is the electric field strength or electric potential?

A graph of V against d...
the gradient would be V/d which is the definition of electric field strength for parallel plates
 
yea e = v/r . V/r is the slope of your graph, 85.
