Surface charges play a major role in DC circuits because they help generate the electric field and potential distributions necessary to move the charges around the circuit. Unfortunately, it is generally regarded as a difficult task to determine the surface charge distribution for all but the simplest geometries. In this paper, we develop a graphical method for the approximate construction of surface charge distributions in DC circuits. This method allows us to determine (approximately) the…

The purpose of this paper is to analyze distribution of surface charge density on DC-carrying conductor. A new numerical analysis method, based on finite element method, is proposed in this paper.
The potentially neglected culprit of DC surface flashover: electron migration under temperature gradients
The results show that the surface potential rises significantly because of electron migration near the high voltage (HV) electrode under high temperature conditions, thus creating an “analogous ineffective region”.
A nonlinear, geometric Hall effect without magnetic field
It is shown that electric current flowing through a curved wire produces a transverse electric potential across the wire, which reflects the sign and density of the current-carrying charges, properties that are traditionally obtained by applying a magnetic field to measure the Hall voltage.
Simple circuits are not that simple
The teaching of basic circuits in early undergraduate physics courses is widespread and, to some extent, quite uniform. In most text books, the introduction of resistors, capacitors and inductors is
