How is Work Calculated in an Electric Field?

Click For Summary
SUMMARY

The discussion centers on the calculation of work done on an electron in an electric field, specifically addressing the equation W = eV. It clarifies that while the potential difference (V) is involved, it is the potential difference that charges move through, not the potential at a specific point. The correct interpretation of work done is confirmed as W = eV, emphasizing that V remains constant during the charge's movement through the field.

PREREQUISITES
  • Understanding of electric fields and potential difference
  • Familiarity with the concept of work in physics
  • Knowledge of kinetic energy (KE) in relation to charged particles
  • Basic grasp of electron charge and energy equations
NEXT STEPS
  • Study the relationship between electric fields and potential difference in detail
  • Explore the derivation of the work-energy theorem in electric fields
  • Learn about the behavior of charged particles in varying electric potentials
  • Investigate the implications of work done on electrons in practical applications
USEFUL FOR

Students studying electromagnetism, physics educators, and anyone interested in the principles of work and energy in electric fields.

Homework Equations


The Attempt at a Solution



now I know this has something to do with energy done on electron and KE.

apparently work done on electron is:
W = eV

BUT surely this implies V is constant. as the charge moves, will not V change?
hence it should be
W = 0.5*eV?
 
Physics news on Phys.org
found it
my book says V is the p.d that charges MOVE THROUGH not are in :)
