What material will hold static charge on its surface?
Any material electrically separated from ground will hold a static charge, even the human body, but only some materials can genate a static sharge in the first place by friction.Run a clear bic ballpoint pen over your hair then hold it close to a fine dribble of water from the tap. It will bend the water because of its static charge. Once the water touches the pen, the charge escapes through the water, up into the tap and then into the earth via the pipes. Note only some plastics generate a static charge in this way.I believe that some materials hold a negative static charge, while others (glass?) hold a positive charge. Not sure though.
What is the process of diverting unwanted electric charge directly into the earth?
That process is called grounding.
When an observer moves past a stationary electric charge she detects?
Love and what not love love will keep you together with the earth
Rubbing one object against another causes a of one kind of charge?
Rubbing an insulator against a non insulator causes the build up of electrons which is known as static electricity, the electrons take the easiest route to earth, that's why if you touch any thing that is earthed you may get an electric shock :)
What does grounded mean as it relates to static electricity?
Grounded, with any electrical circuit, means there is a firm connection to earth, to prevent danger of electric shock or arc discharge.
What are potential health risks associated with static electricity?
As long as the electricity is static, it is of little concern. Of course, static today, current tomorrow. If you are in contact with a large static charge and also with the Earth, the energy can flow through you, and there might be enough to stop your heart. I heard of a man who picked up two cables to connect them and was cooked. The person in charge said it was static electricity, since the power was then not on. Of course, it is my point that static electricity is merely charge, and the charge (most usually) has to move to hurt you. Moving charges are called electric current.
Can you fill electric charge in earth?
no you cant
Is lighting static electricity?
Yes, it is static electricity caused by the charge build up from the movement of air over the earth.
Why it is necessary to earth the star point of three phase circuit?
The star or neutral point is earthed at the supply transformer to prevent the system building up a static electric charge in dry weather.
If the electric field due to the excess charge on the Earth points downward what type of charge does the Earth carry?
negative
Why using earth leads are helicopter refuelling time?
Earth leads protect the helicopter and refuller from static charge.

Are you bound to earth by electric forces or by gravity?
gravity because gravity is dependant on mass and not on charge like an electric field
Where can you find electricity?
Electricity is a very common (actually universal) natural phenomena. It commonly appears in nature as static electricity and static electric discharges, lightning bolts being a very powerful form of static electric discharge. It also appears as electric currents: one natural electric current flows through the outer liquid core of earth forming the earth's magnetic field. Humans have also figured out how to control and "domesticate" electricity for his own purposes, electric current from batteries, generators, and alternators being the most useful form.
What is the process of diverting unwanted electric charge directly into the earth?
That process is called grounding.
What is practically an infinite reservoir of electric charge?
For practical purposes, planet Earth is often considered as such.
Earth's surface has an excess amount of negative charge?
Yes the Earth has a vertical electric field that points down. So if you were to try and calculate the amount of excess charge on the Earth's surface, you would get a negative value.
