Basics of Electronics - In a capsule

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

A 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

A 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

A 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
