The working principle electroscope If an electrically charged object brought near the electroscope, then the electrons in the conductor ball will react according to the type of charge brought near. The working principle electroscope In the example, if the negative charge is brought near, the electrons will move from the tip of a ball into pieces, so the twopieces become negatively charged The result is a repulsive force declined in both pieces so that the two pieces of open.

Giving the charge by touching the electrically charged objects. a) Benda (conductor) brought near the electroscope negatively charged (neutral). b) electron transfer from the object to the electroscope. c) negative electrically charged electroscope. Objects are given an electrical charge by touching, kind of cargothe same as objects that touched .

Gives an electric charge by induction Electrostatic induction is a separation of charges on an object byanother object of the charged. Objects are loaded electrical inducti on, type of cargo as opposed to the type of content objects that induce. At the time of electrically charged object brought near a neutralobject, charge separation occurs at the neutral object. End of theneutral objects adjacent to the object inducer, charged the same as the object of inducer. When the object is connected to earth (for example by touch), the occurrence of electron transfer from or to the earth through the body. Once charged objects away, the object becomes a deficiency orexcess of electrons that a neutral object become electrically charged.

Electric Field and Potential The electric field is the space at each point in which electric charges experience a force of electricity. Having a positive electric charge electric force (repulsive force)because being around other positive charge.

Direction of the electric field

Just like every mass in the gravitational field has gravitational potential energy, then any objects that are electrically charged in an electric field also has an electric potential energy n .

Electric potential of a charge is the magnitude of the electrical potential energy divided by the magnitude of the charge object.
