Engineering Understanding the Relationship Between Voltage and Electric Field

Click For Summary
SUMMARY

The discussion clarifies the relationship between voltage and electric fields, emphasizing that voltage is not a point measurement but rather associated with a path between two points. The equation V=U/q is highlighted, illustrating that voltage represents the potential difference, which is independent of the electric field at a specific point. The conservative nature of electromagnetic fields is also noted, confirming that the potential difference remains consistent regardless of the path taken.

PREREQUISITES
  • Understanding of basic electromagnetism concepts
  • Familiarity with the equation V=U/q
  • Knowledge of electric fields and potential differences
  • Concept of conservative forces in physics
NEXT STEPS
  • Study the principles of electric potential and electric fields in detail
  • Learn about conservative forces and their implications in electromagnetism
  • Explore the concept of potential difference in various contexts
  • Investigate practical applications of voltage in circuits and electric systems
USEFUL FOR

Students in physics courses, particularly those studying electromagnetism, educators teaching electric field concepts, and anyone seeking to deepen their understanding of voltage and its relationship with electric fields.

Hi guys ! I am taking phys102 course .I figured out that i didnt fully understand the concept that is the Voltage. Please look at this question. In this case we can see that there is no voltage in point C and there is no electric field is in point D and as you know V=U/q .So i always thought that voltage is a indicator that shows us how much electric field can do work in a point that is independent from charge q. So i didnt understand how V=something that is diffrent from zero when E=0.

No, voltage is always associated with a path, not a point. But since EM is a conservative, it's also the difference in potential between two points (i.e. how you get from beginning to end doesn't matter).
 
thanks for the reply i get it :)
