How does an electric field come inside a conducting wire inside …
2015年12月28日 · This causes current to flow in a thin layer along the outer surface of the wire. Since the conducting material of the wire has some non-zero resistance, this current in the …
What is the potential difference inside a metal conducting wire?
2018年9月30日 · The wire is neutral because there are as many positively charged protons as negatively charged electrons. When connected to a battery, the electromotive force sets up an …
If the conducting wire isn't isolated (connected to battery)
2024年9月27日 · It is said that if a conducting wire is isolated charges will redistribute itself on the surface of the conductor i.e no internal $\vec{E}$. The $\vec{E}$ field inside of a conductor will …
What happens inside a conducting wire if it is placed in an electric ...
2022年4月30日 · If the field is static, the conductor will be equipotential in the equilibrium state. If you bring the conductor in the field from a region with no field or with a different value of the …
Does electricity flow on the surface of a wire or in the interior?
2014年4月28日 · Surface charge is always required on a conducting wire, in order to establish powerflow over the wire. There are two types of current density $\boldsymbol J$: …
Magnetic field in the cavity of a conducting cylindrical wire
2018年6月25日 · Assuming that you have a infinite long conducting cylindrical wire: Is it possible to let the magnetic field be constant inside the cavity and why?
electrostatics - How to find the distribution of charge on two …
2015年4月17日 · Joining the two spheres with a conducting wire means that charges will flow until the potential difference between the two spheres becomes zero ie there is no electric field …
How is the electric field created by a battery inside a conducting …
A wire is used to conduct electricity along its length. So, in normal usage, with all current parallel to the axis of the cylindrical wire, the electric potential is a function only of the length …
electrostatics - Why is there an electric field in a wire even though ...
2015年12月28日 · The battery obviously causes an electric field at both ends of it, making, for a millisecond, more electrons build up on the piece of wire connected to the negative terminal of …
Potential difference across a zero resistance wire
2018年5月31日 · If potential difference across a tiny cross section of conducting wire is zero, then why on earth does electron flow across that cross section at all? Never mind potential …
