Course Curriculum

Module 01: Introduction and Basics

An introduction to electrical theory and its real-world applications. This module establishes the foundational terms and concepts such as electrical current, charge, and energy. Learners explore the concept of electric circuits, conduction, and insulation, providing the vocabulary and framework for future modules.

Module 02: Electrical Units and Ohm’s Law

A deep dive into the most essential electrical units and how they interact. Key units like volts, amperes, watts, and ohms are explained with visual aids and analogies. The module also explores Ohm’s Law (V=IR), showing how voltage, current, and resistance relate in circuits, and includes practice scenarios to reinforce understanding.

Module 03: Direct Current

Focuses on DC (Direct Current) circuits, commonly found in batteries and electronic devices. Learners will analyze how electrons move in a single direction, study series and parallel configurations, and calculate voltage drops, current flow, and total resistance using standard formulas.

Module 04: Alternating Current Basics

Explains AC (Alternating Current)—the type of electricity used in homes and businesses. Topics include frequency, phase, amplitude, and how AC differs from DC. Learners are introduced to AC waveform analysis, sinusoidal signals, and applications like household wiring and electric motors.

Module 05: Voltage and Resistance

Examines the concepts of electrical potential (voltage) and opposition to current (resistance) in more detail. Learners explore how resistors affect circuit behavior, understand voltage drops, and use calculations to balance power distribution across electrical systems.

Module 06: Capacitance and Capacitors

Introduces capacitors, which store electrical energy in electric fields. Learners study how capacitance is measured (in farads) and how capacitors are used in smoothing circuits, timing functions, and signal filtering. Real-world examples are included to aid conceptual clarity.

Module 07: Magnetism

Links electricity with magnetism, introducing electromagnetism, magnetic fields, and induction. This module covers how electric currents create magnetic effects, how transformers operate, and the relationship between magnetic force and current flow.

Module 08: Safety Precautions

Focuses on essential electrical safety procedures, personal protective equipment (PPE), correct handling of components, and how to avoid short circuits, overloads, and fire hazards. Learners develop practical habits that reduce risk when working with live circuits or power sources.
