Electricity

Electricity

1. Electricity is the set of physical phenonema related to the presence and flow of electricity charges.It manifest itsel in a wide varlety of phenonema such as lightning.

   • Electric Circuit
     • Parts
     • Open
     • Closed
     • Broken

2. Tool

   • Wire strippers
   • Insulated Screwdrivers
   • Insulated Pliers
   • Electrical Type
   • Cable Cutters
   • Voltage Tester

3. Atom: An atom is a particle of a matter that uniquely defines achemical element.

   • Nucleus Orbit: The nucleus is a a collection of a particles called protons, which are positilevy charged, and neutrons, which are electrically neutral. The elctron is a subatomic particle, whose electric charge is negative.
     • Currents
       • Current A.C : Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitudes.
       • Current DC : Direct Current (DC) is one-directional flow of electric charge.
       • Amp: Ampere or ampère (Symbol A) is the unit of electric current intensity. It is part of the base units in the international system of units.
       • Ohms: Ohms or or ohm is the derived unit of electrical resistance in the International System of Units.
       • Volts: The volt is the difference in electrical potencial betwen two points of a conductor that carries a constant current of 1 ampere
       • Conductor: An electrical conductor is a material that offers little resistence to the movement of electrical charge.
       • Insulators: An electrical insulator is a material electrical charges cannot move causing a small magnitude of current under the influence of an electric fiel.
       • Semiconductor: is an element that behaves either as a conductor or as an insulator depending on factor. ej: electric or magnetic, preassure, radiation.
