A uniform electric field exists between parallel plates of equal but opposite charges. (Correct?) For electric field mapping with a general electric field mapping board, the electric field intensity, which can be calculated from the potential difference and distance between any two points, can...
Problem:
A given system has the equipotential surfaces shown below, where Vo = 12.0 V.
(a) What are the magnitude and direction of the electric field?
(b) What is the shortest distance one can move to undergo a change in potential of 5.00 V?
I am not too sure on what equations I...
"For a point charge of +3.50 microC what is the radius of the equipotential surface that is at a potential of 2.40 kV?"
For a point charge, the voltage = kq/r, where k =9*10^9 N*m^2/C^2, q is the charge, and r is the radius. Solving for r, I get r = 13.1 m. But the answer is 12.6m...
just a coupla quick questions:
1) in a parallel plate capacitor, we have field lines and equipotential lines. field lines show direction from the + to the - plate, but equipotential lines have no direction. why is this?
2) what happens to the electric field near the edges of the plates?
3) if...
Hey all,
I'm a bit confused over an experiment in which we mapped Equipotential Surfaces to then use to draw Electric Field lines using electrodes placed into water to act as a dipole. Along with this, we also had to place a circular conductor and insulator (both uncharged) into the water as...
Hello everyone I'm confused on this topic. I read about it in the book and it made sense though. The question is: Figure 24-25 shows three sets of cross sections of equipotential surfaces; all three cover the same size region of space.

We haven't really covered this in class so I need some help.
Assuming that these contours are those of a point charge at the origin, calculate the value of the charge in C.
I tried using the equation kQ/R but that's wrong, I'm not even sure I'm using it right in fact. Any help? Thanks
Field Lines and Equipotential lines
Why can't 2 field lines cross, and why can't 2 equipotential lines cross?
I understand that equipotential lines are perpendicular to field lines. And I see that it'd be impossible to find an equipotential line if two field lines have crossed, since there...
This is the same equipotential lines thread that you may have read
in the Linear and Abstract Algebra.
I have questions…

Indeed, it's me again... asking some questions...
