A Short Circuit
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.
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.
An electric current is the movement of the conduction band electron "gas" in a conductor. This can be induced in various ways:Application of a voltage difference across the conductor.Having magnetic flux lines "cut through" the conductor, which will push the electron "gas" perpendicular to the plane the flux lines "cut".Connecting the conductor to 2 dissimilar metals and placing the metals in an electrolyte. Corrosion of one of the metals will cause current in the conductor.etc.
The trains themselves do not cause pollution, but the source of the power such as a coal burning power plant does.
The electric car was invented so the earth can stay alive and healthy, meaning we humans stay alive 'cause of all the healthy trees and plants.
Electric shocks cause death in 3-15% of cases
Electric shocks can paralyze the respiratory system or disrupt heart action, causing instant death
Electric shocks in the body can be caused by contact with electrical sources such as faulty wiring or appliances. To prevent electric shocks, it is important to ensure that electrical systems are properly installed and maintained, avoid using electrical devices near water, and always use insulated tools when working with electricity. Additionally, using ground fault circuit interrupters (GFCIs) can help protect against electric shocks.
No, electric shocks typically do not cause bruising. They can cause burns or tissue damage at the site of contact, but bruising is not a common symptom. If you have concerns about an electric shock injury, it's important to seek medical attention.
The ability of light to cause electron movement and electric current is known as the photoelectric effect. When photons of light strike a material, they can transfer their energy to electrons, causing them to be ejected from the material, which can then result in the generation of an electric current.
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.
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.
Electric shocks can be harmful for several reasons. The main danger comes from the electrical current disrupting the normal functioning of the body's electrical system, potentially leading to heart arrhythmias or damage to vital organs. Additionally, electric shocks can cause burns and tissue damage at the point of contact with the electricity. Immediate medical attention is crucial following an electric shock to assess and manage any potential injuries.
A galvanometer needle can be moved by the flow of electric current through its coil, the presence of a magnetic field, or mechanical disturbances like vibrations or shocks.
Water is a good conductor of electricity, so mixing electricity with water can cause electric shocks. It is important to be cautious around electrical sources when water is present to avoid potential hazards.
The shocks are there for a reason. Removing them would cause damage.
yes!!
