Taking the vector E out of the Electric potential equation

Click For Summary
SUMMARY

The discussion centers on the relationship between the electric field (E) and electric potential (V) in the context of the integral V = E · dr. It clarifies that E can be taken out of the integral when dealing with a uniform electric field, which simplifies the calculation of electric potential. The participant initially questioned the validity of this assumption, recognizing that E varies with distance in non-uniform fields. Ultimately, the conclusion is that the integral is applicable for uniform fields, providing an approximate value for electric potential.

the Electric field depends on the distance between the electric source and the point of measurement. Why can you take E out of the integral V = E dot dr? After all, E can't be constant from infinity to r sub zero...right? Is the integral supposed to be an approximate value?

need some assistance.

oh, I get it now...it was for a uniform field. never mind.
