Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge.


VOLTAGE is an electromotive force or potential difference expressed in volts.

RESISTANCE of an object is a measure of its opposition to the flow of electric current. Omh¨s






INTENSITY  isthe magnitude of an electric current as measured by the quantity of electricity crossing a specified area of equipotential surface per unit time.Amperes.






OMH´S LAW: a law stating that electric current is proportional to voltage and inversely proportional to resistance.
