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.

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 concept taught by Rahul
During their recent lesson, Rahul and Josh delved into power system protection, specifically reviewing various earthing systems. Their discussion covered solid, resistive, and reactor earthing, examining their practical applications and how they influence relay sensitivity. The pair also initiated a discussion on unit protection schemes, a topic they plan to continue in their upcoming lesson. Rahul committed to sending Josh the annotated file from their current lesson.
Relay Sensitivity & Pickup Setting
Unit Protection
Reactor Earthing (Peterson Coil)
Resistive Earthing
Solid Earthing
Rahul and Jake reviewed electrical engineering concepts, including voltage dividers, LDRs, diodes, and transistors, focusing on circuit design and component selection. Jake worked through problems related to calculating resistance, understanding diode behavior, and determining base current in transistor circuits. Rahul agreed to annotate the assignment and discuss the op-amp section and the second assignment in a follow-up session.
Voltage Divider Rule
Light Dependent Resistor (LDR)
Diode Forward Bias
Transistor Beta (hFE)
Rahul and Aidan worked through DC circuit problems from assessment papers, focusing on calculating meter readings (wattmeters and ammeters) under different switch configurations. They analyzed circuits with series and parallel components, applying KCL and Ohm's Law. They plan to skip the next session due to Aidan's practical tutorial.
Resistance Calculation from Ratings
DC Circuit Analysis
Wattmeter & Ammeter Readings
Open Circuit Impact
Polarity in Voltage Drops
Rahul and Aidan worked through several voltage drop calculation problems from past papers, focusing on correctly identifying and applying the appropriate tables and formulas. They clarified the meaning of "power factor corrected" and its impact on table selection. They plan to cover overload and short circuit calculations in the next session.

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.
