The properties of an electric are that its SI unit is Coulombs, it can be either positive or negative, in a closed system the electric charge is conserved and it produces forces that can attract or repel matter. 

2. Robert Millikan's Experiment shows the charge of an electron. 

3. The electrical charge of an electron is -1.602x 10^-19. The electrical charge of a proton is 1.602 x 10^-19. 

4. An electrical conductor allows the flow of electrical current (metals, aqueous solutions of salt). The solution may conduct through the negatively charged salt.  Insulators prevent the free flow of electric current (air, glass, and plastic). Air does not have a charge and thus prevents the flow of electrons. 

5. Grounded is the reference point in an electrical circuit from which voltages are measured, c common return path for electric current, or a direct physical connection to the Earth.

6. Electromagnetic induction is the production of an electromotive force in a conductor as a result of a changing magnetic field  about the conductor.

7. A field force is a vector field that describes a non-contact force acting on a particle at various positions in space. An electric force is the attractive or repulsive interaction between any two charged objects that relies on no physical contact. 

8. An electric field is a region around a charged particle or object within which a force would be exerted on other charged particles or objects. The electric field formula is E = F/q. E stands for electric field in N/C or volts/m. F stands for electric force in Newtons. q stands for charge in Coulombs. ]]> 2017-04-03 22:00:41 UTC https://padlet.com/tec430/vb6y92mii5am/wish/164487442 Sitara and Jordan https://padlet.com/tec430/vb6y92mii5am/wish/164487701 1.  Electrical charge is measures in the SI unit Coulumb, or 6.242×1018e, where e is the charge of a proton. Charges are positive or negative.
2. Robert Millikan's Oil experiment determined the size of the charge on an electron, the smallest 'unit' charge.
3. electron: -1.602×10−19 C
    proton:  1.602×10−19 C
4. conductors lets currents flow freely while insulators done. Metals like copper are great conductors while fiberglass is an insulator. 
5. Grounded is when the extra charge from an object is transferred from the object to another larger one. 
6. Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.
7.  A field force is a vector that describes a non-contact force acting on a particle at various position.

Electric charges can either be negative or positive. Opposite electric charges are attracted to each other while the same charges repel each other. 
2. Robert Millikan's experiment showed the charge of a single electron: -1.6 x 10^-19 C.
3. The electrical charge of an electron is -1.6 x 10^-19 C. The electrical charge of a proton is 1.6 x 10^-19 C.
4. In an electrical conductor, electrical current can flow freely, while in an electrical insulator the electrical current cannot flow freely. An example of an electrical conductor is gold, and an example of an insulator is rubber.
5. Grounded is when the excess of either a negative or a positive charge is removed from the object.
6. Induction is when a charged object is brought near but not touched to a neutral conducting object, causing an imbalance of electrons, one side being more positive and one side being more negative.
7.Coulomb's law states
8. Electric force is a field force because they both have electrical charges that repeal and have a force on the object's particles.
9. F= (kxq1xq2)/ d^2
10. An electrical field is an area surrounding the charged particle or object.
E= f/q]]> 2017-04-03 22:03:13 UTC https://padlet.com/tec430/vb6y92mii5am/wish/164487718 Diana Rendler https://padlet.com/tec430/vb6y92mii5am/wish/164487722 1. One of the properties of an electric charge is conservation in a  closed system. The charge can be negative or positive and has an SI unit called Coulomb.
2. Robert Millikan's experiment showed that atoms have charge and he found the size charges; the charge was some variety of 1.59 x 10-19 C.
3. The electrical charge of an electron is -1.6021766208(98)×10−19 C and the electrical charge of a proton is 1.6021766208(98)×10−19 C.
4. An elctrical conductor means the outer electrons of an atom are bought loosely and therefore can move more freely through a material. Some examples are copper and most other metals. Insulators are atoms with tightly bound electrons so the electrons have a harder time moving through the material. Some examples are glass and mica. 
5. Grounded means the extra charge from an object is transferred to another object, usually a larger one. 
6. Induction is when a charged object is placed near a neutral object. The proximity of the charged object causes the electrons in neutral object to shift, resulting in one more positive and more negative side within the neutral object. 
6.5  Coulombs' law is 
in which the F stands for force, Q1 represents quantity change in object one, Q2 represents quantity change in object two. The k stands for coulombs law constant and d stands for the distance between the two objects.
7. A field force is a non contact force, so an electrical force is a field force because it is expanded outward from a positive source and directed inward from a negative force.
8. An electric force is a region around a charged particle in which objects move toward or away from the particle.  It is calculated by

Electric charge is also conserved, meaning it is independent of speed. It can attract or repel matter. Electrical charge also appears in quanta.
2. Robert Millikan's experiment showed the charge of an electron and suggested the quantization of electrical charge.
3. e = 1.60217662 × 10-19 coulombs
4. In an electrical conductor, electrical charge can flow freely, while in an insulator it cannot. Examples include copper and rubber, respectively. In a conductor, the outer electrons of atoms are able to move freely in a "sea", while in an insulator there is a strong resistance to electron flow. 
5. Grounded means the excess charge of an object is balanced by the transfer of electrons between the charged object and a ground.
6. Induction is a method used to charge an object without actually touching the object to any other charged object.

k =  8.99×109 N m2 C−2
q1 and q2 = signed magnitude of charges
r = distance between the charges

Electric charge is conserved. The force generated by two charges is of the same form as that generated by two masses and force from an electrical field is both conservative and central. It is a relativistic invariant.  Charge is independent of speed will remain constant.
