Into Electricity!!!

In today's class we were introduced to the unit of Electricity. We used textbooks to match terms with their definitions. From this, we established:



Elementary Charge- the magnitude of the charge on a single proton or electron.

 e=1.602x10^-19C, where C= 1 coulomb



Electric Circuit- A closed-loop conducting path, consisting of a source of electrical energy, a conductor, and a load, which utilizes the electrical energy.



Conductor- known to have an electrical charge because it has excess or a deficiency of electrons. The charge is distributed over the surface of the conductor because of the similar charges’ repulsion.



Electric Current- the rate of which charges flow at- passing through a cross-sectional area in a conductor. It is considered to be a flow of positive charges.



Ammeter- used to measure the electric current in an electric circuit, and is connected in a series with the circuit.



Schematic Diagram- a plan or design which represents the components and their relationship to one another by symbols



Direct Current- the continuous flow of electrons in the same direction



Alternating Current- periodic reversal in the direction of the flow of electrons



Fundamental Law of Electrical Charges:

-opposite electric charges attract each other

-similar electric charges repel each other

-charged objects attract neutral objects



Conduction- is the process in which a neutral object gains a charge through contact with a charged object



Induction- an electrically charged object being used to create an electric charge on another object without touching.



After learning about these concepts, Mr. Banow proceeded to show demonstrations of  Electrostatics. He did so by showing the transferring of charges between a balloon, wall, and sweater. We ended the class with Mr. Banow experimenting with a Van de Graff Generator.
