If a stationary electron sat inside a stationary electric field would the electric field cause the electron to move?
Yes. Stationary electric (electrostatic) fields will act on each other and a force will be developed. If you had a standing electric field and could "beam in" an electron (a la Star Trek), the electron would react at once and move either toward a positive field source or away from a negative field source. The electron would know the field was there the instant it appeared.
What is ambipolar transport?
when a pulse of excess electrons and excess holes are created at a particular point in a semiconductor an induced internal electric field will be present between them. This internal electric field will cause the negatively charged electron and positively charged hole to drift or diffuse together with a single effective mobility or diffusion coefficient.
What is the relationship between electricity and magnetisum?
The magnetic field will be perpendicular to the electric field and vice versa.More DetailAn electric field is the area which surrounds an electric charge within which it is capable of exerting a perceptible force on another electric charge. A magnetic field is the area of force surrounding a magnetic pole, or a current flowing through a conductor, in which there is a magnetic flux. A magnetic field can be produced when an electric current is passed through an electric circuit wound in a helix or solenoid.The relationship that exists between an electric field and a magnetic field is one of electromagnetic interaction as a consequence of associating elementary particles.The electrostatic force between charged particles is an example of this relationship.
What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
What is the definition of reverse leakage current?
Reverse leakage currentin asemiconductordevice is thecurrentfrom that semiconductor device when the device isreverse biased.When asemiconductordevice isreverse biasedit should not conduct anycurrentat all, even though, as a temperature effect, it will form electron-hole pairs (seeCarrier generation and recombination) at both sides of the union and therefore a very small current, which is namedReverse leakage current, and this current doubles for each increment of 10°C in temperature. The current is caused by electron hole pairs being swept across the electric field of the depletion region when generated thermally near the edge.
What is the velocity experienced by an electron in an electric field?
The velocity experienced by an electron in an electric field depends on the strength of the field and the mass of the electron. The velocity will increase as the electric field strength increases. The electron will accelerate in the direction of the electric field.
How does an electron move in an electric field and what factors influence its motion?
An electron moves in an electric field by experiencing a force that causes it to accelerate in the direction of the field. Factors that influence its motion include the strength of the electric field, the charge of the electron, and any other forces acting on the electron.
What actually causes the electrons to move?
Electron movement is primarily caused by an electric field. When a voltage is applied across a conductor, such as a wire, the electric field pushes the free electrons in the conductor to move in a particular direction, creating an electric current.
How does a free electron at rest move in an electric field?
A free electron at rest in an electric field will experience a force due to the field and will accelerate in the direction of the electric field. The electron will gain kinetic energy and start moving in the direction of the force until it reaches a velocity where the force due to the field is balanced by other forces acting on the electron.
If a stationary electron sat inside a stationary electric field would the electric field cause the electron to move?
Yes. Stationary electric (electrostatic) fields will act on each other and a force will be developed. If you had a standing electric field and could "beam in" an electron (a la Star Trek), the electron would react at once and move either toward a positive field source or away from a negative field source. The electron would know the field was there the instant it appeared.
How does the electric potential energy change as the electron moves from one point to another in an electric field?
As an electron moves in an electric field, its electric potential energy changes. This change occurs because the electron experiences a force due to the electric field, causing its potential energy to increase or decrease depending on the direction of its movement.
What will be the effect on the motion of electron if it travels along the dirction of electric field?
If an electron moves in the direction of an electric field, it will experience an acceleration in the same direction as the field. This will cause the electron's motion to speed up. If the electron is already moving with a velocity in the direction of the electric field, it will continue to move with a constant velocity.
What is the field surrounding every moving electron?
An electron is surrounded by an electric field. The electron is negatively charged. A moving electric charge creates a magnetic field. Use the "right-hand rule". Point your thumb up and curl your finger a bit so your hand looks like it is holding a bottle. If the electric charge (e.g. electron) is moving in the direction of your thumb, then the magnetic field it creates moves counter-clockwise in the direction of your fingers.
What is the relationship between the kinetic energy of an ionized electron and its movement in an electric field?
The kinetic energy of an ionized electron is directly related to its movement in an electric field. As the electron moves in the field, its kinetic energy increases, and the speed of the electron also increases. This relationship is governed by the principles of electromagnetism.
When electrons are rearranged in an object by an electric field the object is charged by what?
When electrons are rearranged in an object by an electric field, the object is charged by gaining or losing electrons. If an object gains electrons, it becomes negatively charged, and if it loses electrons, it becomes positively charged.
What is the electric field surrounding an electron It's defined as a force vector or warpage of space around the electron - what is this mysterious field made of what is it in a tangible sense?
The electron is surrounded by an electric field. The electric field can be represented by force vectors in models because the field will act on other fields. It will in concert with another field like it to push away, or act with another field opposite it to draw together. It's fairly simple like that. The "problem" with an electric or magnetic field is that is it invisible. Its effects can be seen, but the field itself, the force itself, is invisible. Like gravity. You can't "grab a handful" of gravity and look at it. And you can't do that with electric or magnetic fields, either. It's just there and it works. It works in accordance with the laws of electromagnetics.
How are electromagnetic waves formed?
they are formed when a electric field and a magnetic field couple. When ever a charged particle undergoes an acceleration it emits electromagnetic radiation. Therefore when an electron 'jumps' from a high energy quantum state to a lower energy quantum state it produces em radiation of a particular frequency. And, more precisely, EM waves are created by accelerating a charge. An electron at rest (or cruising at constant speed) has a stable electric field radiating outwards (really inwards for negative charge). If the electron is accelerated, a ripple in the field radiates outward with the speed of light, with the strongest effect perpendicular to the electron's vector of acceleration and weakest part (zero) along the vector. The electric field fluctuation is in any plane along the vector, and the magnetic part is in the plane perpendicular to that and the vector.
