Resistors, Capacitors and Semiconductors


My course session 1 covers the basics of semiconductors and its classifications

resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

  • Resistance
  • Resistors in Serial & Parallel
  • Types of Resistors
  • Color coding

capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals. The effect of a capacitor is known as capacitance.

  • Capacitance
  • Capacitors in Serial & Parallel
  • Charging & Discharging of capacitor
  • Types of Capacitor
  • Derivation of  Capacitance in each type
  • Derivation of energy stored in a capacitor
  • Derivation of energy density
  • Types of Capacitors (di-electric)
  • Reading capacitor value

semiconductor can be considered a material having a conductivity ranging between that of an insulator and a conductor. A crucial property of semiconductors is the band-gap; a range of forbidden energies within the electronic structure of the material.

  • Energy bands, Valence electrons, and Covalent bonding
  • Classification of materials – conductors, semiconductors, insulators
  • Energy Band Diagram of conductors, semiconductors, insulators
  • Classification of Semiconductors
  • Classification of Extrinsic Semiconductors – P-type and N-type Semiconductors
  • Differences between Extrinsic and Intrinsic semiconductors
  • Differences between n-type and p-type semiconductors.

Section 2 of my course would cover

  • Inductors
  • Transformers
  • PN junction diode

Who this course is for:

  • Engineering & Diploma 1st year students
