WHAT IS ELECTRICITY?

This is a form of energy resulting from the existence of charged particles.
Current Flow and Ohm's Law
Ohm's law is the most important, basic law of electricity. It defines the relationship between the three fundamental electrical quantities:
I= Electrical Current(Amperes):the magnitude of an electric field at a point in the field, equal to the force that would be exerted on a small unit chargeplaced at the point.
V=Voltage(Voltage): is a quantitative expression of the potential difference in charge between two points in an electrical field. 
R= Resistance(Ohm´s):The electrical resistance of an object is a measure of its opposition to the flow of electric current. The inverse quantity is electrical conductance, and is the ease with which an electric current passes.
