CHAPTER I !   ELECTROTECNIA FUNDAMENTAL

CONCEPTS !   Introduction. !   Constitution of matter. !   The electric current. Voltage.

Magnitudes. !   Power sources. Principles of Generation.

CC vs. CA. !   Effects of electrical current. Effects on

the human body. Current ranges. Safety. Behaviour in case of accidents.

Introduction !   The matter is made of tiny units called atoms, neutrons and protons in the nucleus and

electrons in the crust , revolving around the above.

!   Protons are positively charged and electrons negatively .

!   Each material is formed of one type of atom which is different from another in the number of subatomic particles has . Normally the atoms tend to have the same number of electrons as protons , so its total charge is neutral as loads of different particle counter .

!   Thus , hydrogen ( H ) is formed by an electron, a proton and a neutron , helium (He) by two , the Cu by 29 electrons , 29 protons and 29 neutrons.

! Video: Atoms

!   Atoms sometimes suffer a variation in the number of electrons , then the atom acquires electric charge, which is positive when one electron is lost ( since the number of electrons is smaller than that of protons ) and negative when acquiring new electrons .

!   When , for any reason, the total load is no longer zero , the atom tends to give or take electrons from nearby atoms to return to its equilibrium state .

!   The movement of electrons occurs to achieve load balancing between different atoms is the electrical phenomenon and the work done during the movement of electrons, it’s named electricity.

What  is  electrical  engineering?  

The  study  of  ELECTRICITY  along  with  its  numerous  applica<ons  

A  brief  history  In  1600,  William  Gilbert  called  the  property  of  aDrac<ng  par<cles  aEer  being  rubbed  “electricus”.  

De  Magnete  was  a  trea<se  of  electricity  and  magne<sm,  no<ng  a  long  list  of  elements  that  could  be  electrified.  

A  versorium  

Gilbert  invented  the  versorium,  a  device  that  detected  sta<cally-­‐charged  bodies  

William  Gilbert,  arguably  the  first  electrical  engineer  

A  brief  history  1800  –  voltaic  pile  developed  by  Alessandro  Volta,  a  precursor  to  the  ba#ery  

1831  –  Michael  Faraday  discovers  electromagne/c  induc/on  

1873  –  Electricity  and  Magne3sm  published  by  James  Maxwell,  describing  a  theory  for  electromagne/sm

So  where  is  the  field  of  study  now?  

Fields  of  study  

Power:    Crea<on,  storage,  and  distribu<on  of  electricity  

Control:    Design  of  dynamic  systems  and  controllers  for  the  systems  

Electronics/Microelectronics:    Design  of  integrated  circuits,  microprocessors,  etc.  

Signal  Processing:  Analysis  of  signals  

Telecommunica<ons:    Design  of  transmission  systems  (voice,  data)  

Computer:    Design  and  development  of  computer  systems

Electric  current  

An  ampere  (A)  is  the  number  of  electrons  having  a  total  charge  of  1  C  moving  through  a  given  cross  sec<on  in  1  s.
