Electric Field lines running high to low voltage

Click For Summary
SUMMARY

The discussion centers on demonstrating that electric field lines run from higher voltages to lower voltages using the equation Vb - Va = -∫ab (E · ds). The voltage range in the experiment is from 0 to 6 volts, supplied by a DC power supply. Additionally, it is established that electric field lines are perpendicular to equipotential lines, reinforcing the relationship between electric fields and voltage gradients.

PREREQUISITES
  • Understanding of electric fields and potentials
  • Familiarity with calculus, specifically integration

Homework Statement


Show from the given equation Vb -Va=-intergral a to b (E x ds) that the electric field lines run from higher voltages to lower voltages. Also show from this equation that the electric field lines are perpendicular to equipotential lines.

The voltage in our experiment ran from 0-6 across the conductive paper (provided by a dc power supply.

Homework Equations


Vb -Va=-intergral a to b (E x ds)

The Attempt at a Solution


I don't really know where to get started

6-0=-integral(E x ds)

Please point me in the right direction.
