# Electric Field Mapping

## Homework Statement

If i have a sketch of field lines, and equipotential lines which i completed in a lab, and i know the voltage,V, of points located at intervals ,L, how do i find the electric field for the whole plane?

## Homework Equations

lEl = DeltaV/DeltaL

## The Attempt at a Solution

I can find the electric field magnitude for each individual point that i plotted because my distance L was 1cm(constant) and i recorded the voltage at each point.

Welcome to the PF. It sounds like you are on the right track. Can you scan your drawing and post it so we can check it?
