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
