Semiconductor Diodes, Rectifiers, and Waveshaping Circuits
1. Scientific Formulas in Electronics
Q1. Explain the three kinds of formulas with examples.
- Definition: A formula invented for a new concept. It is accepted as true by agreement. Example: C = Q / V, R = V / I.
- Law: A formula describing a relationship that already exists in nature. It is true because experiments verify it. Example: Coulomb’s Law, F = k · (Q₁Q₂) / d², where k = 9 × 10⁹ N·m²/C².
- Derivation: A formula obtained from other formulas using mathematics. It is true because mathematical
Structural Loads, Foundation Engineering, and Seismic Design
1. Types of structural loads
a structural load is a force or action acting on a building that produces stress, strain, deformation or displacement. Proper assessment of loads is essential because structural failure can occur when the load-carrying capacity of a structure is lower than the actual load acting on it. Structural loads may produce compression, tension and shear. Tos v unit 01 part i 2026
1. Dead load
dead load is a permanent or stationary load acting throughout the life of the structure.

DBMS Unit 2: Relational Database Model
1. The Relational Model
The relational model is a data model that represents a database as a collection of relations (tables).
Each relation consists of:
Rows → Tuples
Columns → Attributes
The relational model was proposed by E. F. Codd in 1970.
It is categorized as an implementation/representational data model.
