Electrical Overview


Good day my reader……

The term of electrical is related to definition of electric or electricity.

Electricity is a condition of subatomic particles, such as electrons and protons that cause withdrawal and rejection of such style. Electricity was caused by an electrical charge that flows from a negative to positive channels.

With Maggnetism, fundamental of electricity interaction know as electromagnetism.

The results from the flow of electrons is known as the Electric Energy or Electrical Energy. Where the electrical energy divided into two parts:

  1.  Static Electricity Energy (Electric Static)
  2. Dynamic Electrical Energy (Electric Dinamic)

Static Electricity is a potential electrical energy generated by static discharges for example Lightning, friction 2 objects, etc.

Dynamic Electrical Energy is electrical energy generated by the change in mechanical energy into electrical energy or electrical energy into mechanical energy for examples Generator, Power, etc.

The electrical terminology is:
  1. Current  is the movement of electrical charge
  2. Resistance is opposition to current flow
  3. Voltage is a measure of electrical force
  4. Conductors is substances, such as metals, that have little resistance to the electricity,
  5. Insulators is substances, such as wood, rubber, glass, and bakelite, that have high resistance to electricity,
  6. Grounding is a conductive connection to the earth which acts as a protective measure.

On the next post I will share about electrical installation on:

  • Shipbuilding,
  • Platform,
  • Petrochemical,
  • Power plant, etc.
