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?
