Charging an earthed metal object would cause the charges to be quickly neutralized by the earth's conductor. Since the earth is a good conductor of electricity, any excess charge on the metal object would dissipate rapidly into the ground, preventing the object from holding a charge.
the charge on all alkali metal ions is 1 +
The charge is +3
When you charge the end of a plastic comb and then transfer that charge to a round metal ball, the charge on the ball quickly spreads out to the entire surface due to the conductive nature of the metal ball. The charge on the comb is transferred to the entire surface of the ball, resulting in a more evenly distributed charge across the metal ball.
This depends on each metal.
Charging an earthed metal object would cause the charges to be quickly neutralized by the earth's conductor. Since the earth is a good conductor of electricity, any excess charge on the metal object would dissipate rapidly into the ground, preventing the object from holding a charge.
Earthed metal plates are hit with a hammer to discharge any built-up static electricity. When the metal plate is struck, the excess charge is transferred through the hammer to the ground, effectively neutralizing the plate. This prevents any potential hazards or interference that may arise from the static electricity.
Lorries that transport inflammable liquids, gases and powders must be earthed. This is because when a lorry drives along the road the rubbing of it's tires against the tarmac creates an electrostatic charge build up on the metal chassis of the vehicle. When unloading the load from the lorry this charge may be released and cause a spark as it tries to reach ground. In turn this spark can ignite the inflammable substance and potentially be very dangerous. By eathing the lorry the charge will not create a spark as it tries to dissapate into the earth instead it will go through the path of least resistance (whichever way the lorry is earthed) and be safely discharged.
Connect it to the main part of the metal cabinet, anywhere. It is only important that you are earthed. You can earth yourself by attaching to another item on you desk that is earthed. Soldering iron tip, toaster etc.
No, static electricity cannot build up on a conductor that is properly grounded (earthed). Grounding provides a path for the excess charge to flow into the earth, preventing the accumulation of static electricity on the conductor.
On their own metals have no charge. Metal ions have a positive charge.
Earthed to the Ground was created in 1984-05.
the metal that serves as the best conductor of electric charge is the METAL
the charge on all alkali metal ions is 1 +
generally tertiary wndng is delta .if one point of this delta is earthed(through a CT) then it is not a earth fault. thansformer will operate normally. now if a second point(or any point on the delta winding) is earthed (earth fault) then the fault current will be sensed by the said ct.and Transf will tripped.

As aircraft fly through the air, the friction causes them to become charged with static electricity. After an aircraft has landed there is a possibility of charges escaping to earth as a spark. Therefore, the aircraft should be earthed with a conductor as soon as it lands, allowing the charge that has built up to flow to earth.
