Why can't one charge an earthed metal object?
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.
What is the charge on an alkali metal ion?
the charge on all alkali metal ions is 1 +
What is the charge on the metal in the compound M2S3?
The charge is +3
If you charge the end of a plastic comb and then put the same charge on the surface of a round metal ball what would happen to charge in each case?
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.
When a metal becomes a ion what is its net charge?
This depends on each metal.
Why can't one charge an earthed metal object?
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.
Why are earthed metal plates hit with a hammer?
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.
Why do lorries some lorries need to be earthed?
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.
How do you connect AS wrist strip on a PC?
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.
Can static electricity build up on an earthed conductor?
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.
Do metal ions have a positive charge?
On their own metals have no charge. Metal ions have a positive charge.
When was Earthed to the Ground created?
Earthed to the Ground was created in 1984-05.
Which metal serves the best conductor of electric charge?
the metal that serves as the best conductor of electric charge is the METAL
What is the charge on an alkali metal ion?
the charge on all alkali metal ions is 1 +
Why secondary winding and metal core earthed at one point?
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.

What is the charge on the metal in the compound M2S3?
The charge is +3
Why the aircraft should be earthed?
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.
