Potential difference to find the magnitude of the electric field strength

Click For Summary
SUMMARY

The discussion centers on calculating the electric field strength using potential difference between two oppositely charged plates. The key formula established is E = ΔV / d, where E represents the electric field strength, ΔV is the potential difference, and d is the distance between the plates. A specific example highlights confusion regarding potential differences in varying contexts, particularly when dealing with equipotential lines. The participants emphasize the importance of understanding the reference point for potential differences in electric fields.

PREREQUISITES
  • Understanding of electric fields and potential difference
  • Familiarity with the formula E = ΔV / d
  • Knowledge of equipotential lines and their significance

what are the components to find the magnitude of the electric field strength when only potential difference and that there are two oppositely charged plates that are separated by a given distance.

Welcome to the PF. You must post your thoughts and the relevant equations, before we can offer tutorial assistance. There are basic equations for what you are asking, and they should be listed in your textbook. If you have no textbook, you can use wikipedia.org to look for information like this as you learn.
 
I'm having a similar trouble. I know that E= deltaV / distance but in my book there is a problem where the the point of question (0V) is a distance 1cm from the next equipotential line (200V). The delta V is 200V. BUT in this other problem there are ovular circles around 0V and the equipotentials are 25V, 50V, 75V, and 100V. There is a point on the 50V line and the book says the delta V is 75V... What gives? Why is the delta V not 50V?
