Practical Electrical Engineering, Explained Clearly.
Electrical Engineering by Prasun Barua is an independent educational resource focused on practical electrical engineering concepts, calculations, solar PV and technical guides.
About Electrical Engineering by Prasun Barua
Electrical engineering connects theoretical knowledge with practical application. A formula is useful only when you understand where, why and how to apply it.
Electrical Engineering by Prasun Barua was created to provide clear explanations, engineering calculations, technical guides and educational resources for people interested in electrical technology.
The goal is to explain engineering concepts clearly, demonstrate calculations step by step and provide practical context for real-world electrical systems.
What You Will Find
The site brings together several areas of electrical engineering and renewable-energy knowledge.
Electrical Fundamentals
Voltage, current, resistance, power, energy, circuits and other essential electrical concepts.
Electrical Calculations
Practical formulas, worked examples, voltage drop, power calculations and other engineering calculations.
Solar PV Engineering
Solar photovoltaic fundamentals, system concepts, energy estimation and practical engineering topics.
Electrical Design
Cables, protection, earthing, distribution and practical electrical design considerations.
Our Approach
Good engineering education should be technically accurate without becoming unnecessarily difficult to understand.
Where appropriate, articles use equations, tables, diagrams, practical examples and step-by-step calculations to explain not only the result, but also the reasoning behind it.
Real engineering projects can involve standards, manufacturer requirements, installation conditions, protection coordination, utility requirements and project-specific constraints.
Information published on this site is therefore intended as educational and reference material. Project-specific engineering work should be independently verified by appropriately qualified professionals.
