lesson 1

• determines the electric interaction and magnetic interaction between subatomic particles and other charged particles. is a fundamental physical property that causes objects to feel an attractive or repulsive force toward one another.

  electric charge
• electric charge is represented by the symbol


  q
• measured using the unit

  coulomb(c)
• 1 coulomb 


  6.242x10^18e
• charge implies that any observed charge in nature is a multiple of this elementary charge. This means that the charge is either zero or a multiple of the basic unit e.

  quantize
• the subatomic particles provide

  net charge
• passive electronic component that temporarily stores

  energy in a magnetic field when electric current flows through the

  inductor's coil.

  inductor
• SI Unit of Inductance is

  Henry or H
• Henry came from


  Joseph Henry
• common exmple of inductors 


  solenoid, toroid and coils
• possess a high resistivity and low conductivity.

  insulator
• materials that allow electrical charges to move from one material to another

  conductors
• Conductors may be charged through different methods

  rubbing, conduction and induction
• This property of conductors that allow them to conduct electricity is known as

  conductivity
• The flow of electrons in a conductor is known as the

  electric current
• force required to make that current flow through the conductor is known as

  voltage
• is a list of common materials that were

  experimented on and found to behave in a predictable way.

  triboelectric series
• charging method that charges an object without actually touching the object to any other charged object.

  induction charging
• The separation of electrical charges to opposite poles due to induction is known as

  polarization
• Charging an object by induction may also occur through a

  grounding
• process wherein an electrically neutral body becomes polar by the rearrangement of its molecules.

  polarization
• refer to atoms bearing a positive side and a negative

  point dipole
• This type of dipole involves a molecule having a negatively charger side and a positively charge side

  molecular dipole
• molecule form the negative end of the molecule,


  electronegative atoms
• responsible for the positive end.

  electropositive atoms
• atom or a molecule with most of its negative charges shifted only to one side as a result of their random movement


  instantaneous dipole or temporary dipole
