About your engineering tutor

Hi there! I’m Rahul Sagwal, and I’m thrilled to be your go-to online tutor for all things Electrical Engineering. With over 10 years of experience spread across academia, industry, and research, I bring a unique, real-world perspective to every session. Whether you're a curious first-year student, someone struggling with circuit theory, or a final-year undergrad looking to ace power systems or machine learning applications in EE —I’ve got you covered! I’m currently pursuing my Ph.D. at IIT Kanpur, focusing on the intersection of Electric Vehicles (EVs), Smart Grids, Machine Learning, and Policy Design. Prior to it, I worked as an Assistant Professor for over five years at different locations (different states across India, including Rajasthan, Uttarakhand, Madhya Pradesh, Haryana, Uttar Pradesh), guiding hundreds of diverse students in core electrical subjects like Power Systems, Control Systems, Electrical Machines, and Renewable Energy. My industry experience at JSW Steel as a Junior Manager helps me connect theoretical knowledge to practical scenarios, making your learning journey exciting and application-driven. I've done B.Tech in Electrical Engineering and M.Tech in Renewable Energy Systems, both degrees with first division and from NIT Kurukshetra. Oh, and did I mention? I love simplifying complex topics to the extent that I can. Students often tell me, “Sir, why don't you teach the other subjects too?” and "It's a blessing to have you as our teacher, especially for us who are entering from the diploma to the B.Tech program." So, if you’re looking for someone who’s patient, passionate, and practical — let’s connect. Book a session with me, and let’s turn Electrical Engineering into your superpower!

Engineering class overview

My Teaching Methodology – Making Electrical Engineering Simple, Structured, and Stimulating Over the years, I’ve realized that no two students learn the same way — and that’s the heart of my teaching philosophy. My goal is to transform complex Electrical Engineering concepts into clear, relatable knowledge that students not only understand but can confidently apply in real-world contexts. 1. Conceptual Clarity Comes First I strongly believe that a solid foundation is the key to mastering any subject. 2. Interactive, Not One-Way Teaching Instead of traditional lecture-style teaching, I foster a highly interactive environment. I encourage questions, promote discussions, and involve students actively during sessions. 3. Visual Learning Tools & Simulations For abstract concepts like signal flow, I integrate diagrams, simulation tools (like MATLAB or Python, if needed), PPTs, relevant animation/videos into lessons. These tools make invisible phenomena visible and measurable, which significantly improves retention and interest. 4. Customized Approach for Every Learner I don’t believe in one-size-fits-all learning. Before diving deep, I assess each student’s current understanding and learning preferences. Some students need more practice, others need visual reinforcement, and some just need a better explanation. My sessions are designed to be adaptive and personalized, ensuring that every student progresses confidently at their own pace. 5. Beyond Books—Mentorship & Motivation Many students struggle not because they lack talent, but because they lack guidance. I make it a point to mentor my students beyond academics (only if asked for). To sum up, if students leave a session saying, “Now I get” it!”—I know I’ve done my job well.

Engineering concept taught by Rahul

Josh learned 9 days ago

During a recent lesson, Rahul and Josh delved into power system protection, specifically discussing earthing systems, fault types, and their causes. Rahul elaborated on the critical role of earthing in ensuring safety, protecting equipment, and mitigating transient overvoltages. Following the discussion, Rahul committed to providing Josh with a written summary and feedback on his prior work, and they arranged subsequent lessons to continue their comprehensive review.

Aidan learned 11 days ago

Rahul and Aidan worked through several sample problems related to electrical cable selection, focusing on how to use code book tables to determine the minimum cable size for different installation scenarios. They practiced applying derating factors for cable depth and spacing and reviewed past exam questions to identify common problem variations. Rahul assigned additional practice problems from past papers and mentioned that the next session would cover cable selection when voltage drop is a factor.

Aidan learned 19 days ago

Rahul tutored Aidan on cable sizing calculations using code book tables, focusing on factors like maximum demand, installation method, and derating factors. They worked through sample questions, identified relevant tables, and discussed how to handle parallel connections. Aidan will send Rahul reference materials for review, and they plan to continue practicing with sample papers and regulations next week.

Ash learned 21 days ago

Rahul and Ash discussed delta connections in three-phase electrical systems, including voltage and current relationships, applications, and calculations. They analyzed example problems related to open delta connections, phase reversal, and single-phasing scenarios in both star and delta configurations. They scheduled a follow-up session to discuss three-phase power systems.

Aidan learned 25 days ago

Rahul and Aidan worked through examples of calculating maximum demand for non-domestic electrical installations, focusing on hotels and factories. They used Table C2 to determine appropriate load calculations for lighting, sockets, motors, and welding machines, emphasizing the importance of nameplate ratings and duty cycles. Next session, they plan to cover cable sizing and cable ratings.
