- Separation of Variables to Laplaces Equation in Electrostatics
The discussion focuses on the application of separation of variables to solve Laplace's equation in electrostatics, emphasizing the importance of clarity in mathematical notation Participants highlight the need for using LaTeX for better readability and quoting capabilities A specific question regarding the potential at the center is noted as unanswered, indicating a gap in the solution
- Electric field Difference between Electrostatics and Electrodynamics . . .
Hello everyone, I have been pondering on the behavior of the E field in conductors In electrostatics (where the charges are not moving): a) Electric fields are time- independent but position-dependent b) Electric fields are always zero inside a charged or uncharged conductor At the
- Formal difference between electrostatics and magnetostatics
I thought the first of the two equation applies to electrostatics, and the second one to magnetostatics? So my question essentially comes down to which one (s) of the above equations applies to electrostatics and which one (s) to magnetostatics
- Are electric circuits considered as electrostatics or electrodynamics . . .
Electric circuits are categorized within multiple branches of electromagnetic theory, including electrostatics, magnetostatics, and quasistatic models DC circuits can be analyzed using electrostatics when in equilibrium, while AC circuits often employ quasistationary approximations that consider both electric and magnetic fields The complete understanding of electromagnetic phenomena is
- Electrostatics (four equal point charges) • Physics Forums
Homework Statement Four equal point charges q = +22 4 μC sit at each corner of a square What charge Q, in μC, must be placed in the center so all the charges are in equilibrium? Your answer must include the sign of the charge Homework Equations F = q1*q2 * k r^2 3 The Attempt at a
- Why Is Work Positive When Done Against the Electric Field?
I have several questions relating to electrostatics: first of all, in this derivation for the formula of the electric potential energy: work is being done against the electric field right, so the work should be negative, but in this case it's positive I'm wondering if it's because the direction
- Proof on a uniqueness theorem in electrostatics - Physics Forums
Homework Statement Prove that the field is uniquely determined when the charge density ##\\rho## is given and either ##V## or the normal derivative ##\\partial V \\partial n## is specified on each boundary surface Do not assume the boundaries are conductors, or that V is constant over any given
