    Equipotential Lines: Field Uniformity & Electric Field Mapping

    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...

    Electric Field and Potential Change in a System with Equipotential Surfaces

    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...

    Equipotential surface

    "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...

    Electric field and equipotential lines

    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...

    E-Field Lines and Equipotential Surfaces

    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...

    Ranking E field in equipotential surfaces, confused

    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. Diagram: http://www.webassign.net/hrw/25_29.gif (a)...

    Equipotential Contours and Point Charge

    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

    Force Lines and Equipotential lines

    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...

    Equipotential Lines: Questions & Answers

    This is the same equipotential lines thread that you may have read in the Linear and Abstract Algebra. I have questions… 1. Why don't birds sitting on power cables atop transmission posts get electrocuted? Why do boys get electrocuted when the thread of the kite they are flying...

    Draw Equipotential Lines & Understand Electrical Fields

    Indeed, it's me again... asking some questions... 1. Why don't birds sitting on power cables atop transmission posts get electrocuted? Why do boys get electrocuted when the thread of the kite they are flying accidentally touches a power cable? 2. When you walk across a carpeted floor and...
