In order to build up a charge does a material need to be a conductor or an insulator?

no....absolutely not...to acquire charge, either the material(atoms to be specific) must lose some electrons or gain some....eg. rubbing a glass rod and wool

Is the picture tube a conductor or an insulator Explain your answer?
A picture tube is an insulator. The electrons would gather up and so, create an electric charge when the TV is on. If it was a conductor, the charge would not build up. Hope this helps :)
What does electrica?
Static electricity is the accumulation or build up of electricity charges on the surface of a material, usually an insulator or non-conductor of electricity.
Why does an electric discharge occur?
It is because there are a build up of electrons on a material. If it is static it can be plastic or paper etc . The electrons are surplus to atomic requirements of the material so a negative charge will build up. If the charge is big enough the electrons will try and find a positive source to neutralise the charge. The only thing stopping it from doing so is the insulating material such as air
Accumulation of electric charges on a object?
The build up of a charge on an object can be referred to as a static build up charge.

What will happen if you nearly touch charged insulator?
An insulator does not generally hold a charge, in fact they resist the flow of electrons, this is what makes them insulators. In some cases though, you can build an electrical charge by rubbing a material (usually fibrous like carpet, wool or hair) with an insulator, though not all insulating materials under all conditions. Mostly this works in cold dry conditions because the air itself will act as an insulator not allowing the static electricity to dissipate through the atmosphere. This is why you get shocked in the winter more than in the summer when you grab a doorknob. As for the charge now accumulated on the insulator, think rubber balloon rubbed on hair, It will tend to stay there until it finds a path to ground. Then the charge will dissipated from the area surrounding the contact, but the areas further away may not dissipated because the electrons can not move across the insulator. To sum it up, the electrical charge will transfer to the conductor but an insulator will not charge under normal circumstances.
Is a pencil an insulator or conductor of electricity?
Note: "electricity" is not conducted, only electrical current (the flow of electrons) is. Electricity is the field that covers all things electrical. The wood in a pencil is an insulator. If it is wet, it is a poorer insulator, but only a poor conductor. The carbon (lead) in the pencil is a poor conductor. The metal holding the eraser is a good conductor. The rubber eraser is a poor conductor. You really have to address the conductivity of specific substances, not items that are build from a variety of substances.
How can build up of electrostatic charge be prevented?
Through the use of an earthing conductor, for example the black plastic strips that hang from the rear of a car.

What happens when there is a build up of an electric charge on an object?
When there is a buildup of electric charge on an object, it can create an electric field around the object. If the charge is strong enough, it can lead to sparking or discharge to release the excess charge. This can be observed in phenomena such as lightning or static electricity discharges.
Is an eletrical insulator a metal?
No it would be something like glass... A perfect insulator would have no conductivity, but in real life these don't exist so we tend to use things that have tightly bonded electrons that won't allow a charge to build up.
Is cement a good conductor of heat?
CEMENT DOES NOT CONDUCT ELECTRICTY OR HEAT BUT IT MAY ACT AS A BARRIER TOWARDS THESE ELEMENTS. CEMENT IS NOT GENARALLY USED AS AN INSULATOR BECAUSE ITS MENT FOR HOLDING OBJECTS TOGETHER (LIKE A GLUE). I SUPPOSE IT COULD BE USED AS AN INSULATOR FOR EXAMPLE YOU COULD BUILD A WALL OF CEMENT AROUND YOUR SELF WHEN YOUR IN A BLIZZARD AND IT WOULD BE WARMER ON THE INSIDE THAN OUTSIDE BECAUSE IT ACTS AS A BARRIER TO KEEP THE WIND AND COLD OUT. I HAVE ADDED DEFINITIONS FROM WIKIPEDIA FOR INSULATORS.Insulator (electrical), a substance that resists the flow of electric currentInsulator (genetics), an element in the genetic codeThermal insulation, a material used to resist the flow of heatBuilding insulation, a material used in building construction to prevent heat lossA Mott insulator, a type of electrical insulatorLOL
How much to charge to build a deck not including materials?
It certainly depends on location, material type, and skill level. If you are a professional carpenter you could probably charge about $10 / sq ft.
Can a circuit have more than one insulator?
Yes, depending on how you build it.
Rubbing one object against another causes a of one kind of charge?
Rubbing one object against another can cause a transfer of electrons between the two objects. This transfer of electrons can result in one object becoming positively charged and the other becoming negatively charged.
