Each object that has been charged depend on whether object that is made of a conductive or a nonconductive material.

Conductors

Conductors are materials that permit electrons to flow from particle to particle.
The charge can be transferred to the entire surface of the object if the object is made of conducting material. It’s possible thanks to the electrons’ movement. the charged conductor can even transfer its charge to another object with a touch. Metals such as copper are conductors. Other materials that are sometimes used as conductors are silver, gold, and aluminum.

Insulators

Insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule. If charge is transferred to an insulator, the excess charge will remain at the initial location of charging. The particles of the insulator do not permit the free flow of electrons; then charge is distributed on the surface of an insulator. Insulators don’t transfer charge, they only have a role in electrostatic experiments and demonstrations. Most non-metallic solids are good insulators (plastics, wood, glass, air, paper.) because they can resist to the flow of electric current. Insulators are used to protect us from the dangerous effects of electricity which flows through conductors.

Consideration

Our bodies will conduct electricity and everyone experienced this when has received an electrical shock. Generally, electricity which flows through the body is not pleasant and can cause injuries. The function of our heart can be disrupted by a strong electrical shock and the current can cause burns. We should protect our bodies from the conductors that carry electricity. 

A typical cable for the transport of the current is made of a core of conductor (ex a copper wire) covered by an insulating sheath (ex made of plastic). When the body acquires a static charge it has a tendency to distribute that charge throughout the surface of the body. Given the size of the human body, relative to the size of typical objects used in electrostatic experiments, it would require an abnormally large quantity of excess charge before its effect is noticeable. The effects of excess charge on the body are often demonstrated using a Van de Graaff generator. When a student places their hand upon the static ball, excess charge from the ball is shared with the human body. Being a conductor, the excess charge could flow to the human body and spread throughout the surface of the body, even onto strands of hair. As the individual strands of hair become charged, they begin to repel each other.
