Physics - Electric Current 🔌💡 Definition, how it flows, and what materials allow the flow of electric current

Translated by GoogleSee original

From 4 C$ /h

Physics is one of the sciences that explains and clarifies many of the natural phenomena that occur around us.
One of these phenomena is electricity... The question now is, what is electric current and how does it reach us?
In short, electric current is very similar to the flow of water inside a pipe or water tube. It is considered a large flow of electric charges or free electrons that flow through conductors - metals - such as copper.

I hold a PhD in Mechanical Engineering and currently work as a post-doctoral researcher in the Aerospace Engineering Faculty at TU Delft (Delft University of Technology).

My extensive teaching experience covers a wide range of engineering courses, including:

- Mathematics: algebra, linear algebra, probability, calculus, differential equations, intellectual math, and advanced engineering mathematics.

- Mechanical Engineering: Statics, Dynamics, Mechanics of materials, Mechanical design, control, vibration, Fluid Mechanics, Thermodynamics, Heat transfer, Engineering drawing, Applied Mechanics, Composite Structures, Flight, Machine Elements, Manufacturing, 3D printing, and more.

- Physics: mechanics, momentum and energy, electricity, charge and current, electric and magnetic fields, waves, particle physics, nuclear decay, astrophysics, cosmology, oscillations, etc.

- CAD/CAM Software: Autocad, Solidworks.

- Mechanical Design Packages: ANSYS, APDL programming, ABAQUS, MATLAB, Symbolic MATLAB, LS-DYNA.

My research and teaching interests are diverse, including:
• Additive manufacturing
• Mechanical metamaterials

I understand that not all teachers excel in teaching Engineering and Mathematics courses and explaining their importance to students. Courses with strong mathematical backgrounds may become boring for students who lack a solid mathematical basis. To address this, I take a student-centered approach, starting from the basics to actively engage all students, including those with weaker mathematical backgrounds. I also provide practical examples to demonstrate the real-world significance of what they are learning, inspiring and fostering their interest in the subject matter.

If you have any additional questions before starting a class, please feel free to ask me. I am here to assist! :)

If you’ve ever felt that science and math are difficult, it’s probably because no one showed you how to think like a problem solver.
In my classes, you’ll learn not just formulas or code but how to truly understand concepts, apply them, and build strong logical intuition.

I teach:
• 🔢 Mathematics: From algebra and calculus to applied problem-solving for real-world use.
• 💻 Computer Science: Coding fundamentals (Python, C++), algorithms, and logical thinking for beginners and intermediate learners.
• ⚛️ Physics: Mechanics, thermodynamics, and practical examples that make abstract ideas simple and visual.

As a Software Engineer and Master’s student in Engineering at Nagoya University, I bring both academic knowledge and hands-on experience from real projects. My teaching approach is interactive, visual, and deeply focused on understanding over memorization.

Let’s turn complex problems into clear, step-by-step insights — and make learning something you genuinely enjoy.

Passionate & empathetic teacher. I have a Master's in Physics with honors from the University of Leicester (which was featured at the time as a top 5 Physics university in the UK by The Guardian) and a - french - European School diploma in which I achieved 90% in Physics and 85% in Maths.

Helping others understand difficult topics and skills is something that I am very passionate about as an empathetic person. I have 6 years of experience teaching Physics and Maths to kids from unprivileged backgrounds both in a homework schools as well as via private teaching. In private teaching, I have experience tutoring people with learning disabilities (ADHD, Dyslexia, Discalculia and more), younger kids of ages 7-12 and older students preparing for their final baccalaureate exams in advanced maths/physics curriculums.

In my classes, I aim to:

- help students achieve better grades in exams/tests in all branches of Physics & Maths
- clearly explain and break down topics
- give context and or example applications of topics (to improve understanding and memorization)
- help with ADHD & other learning disabilities
- give practical advice for university applications (eg. UCAS in the UK) and discuss the exciting Physics research/work and projects you can work on later in life.

Physics has a plethora of useful and fascinating applications, from the detection of Gravitational Waves and Gamma-Ray Bursts to the development of novel Medical Imaging techniques and Nano-technology (eg: smartphones). It is a subject that I am very passionate about and I hope to make use of my years of experience and extensive knowledge to help you understand and love the subject! My lessons will always be tailored to the individual needs of the student, so please do not hesitate to contact me if you have questions!

Struggling with math, physics, or chemistry? You're not alone — these subjects are hard, and classroom explanations are rarely enough.
I offer personalized tutoring for middle school, high school, and early university students following the French Mission curriculum, the Moroccan national curriculum, or the international baccalaureate.
Topics covered:

Mathematics: algebra, geometry, calculus, trigonometry, probability
Physics: mechanics, electricity, optics, thermodynamics
Chemistry: organic, inorganic, stoichiometry, reactions

My approach:
I don't re-explain the textbook — I identify exactly where your understanding breaks down and fix it from there. Each session is built around your specific difficulties, not a preset program.
I completed CPGE (Classes Préparatoires aux Grandes Écoles) in Mathematics and Physics before graduating as a State Engineer — I know these subjects at an advanced level and I know where students typically get lost.
Individual and small group sessions available. Online (worldwide) in French, Arabic, or English.

Math, calculus and physics can sometimes be overwhelming, especially when the theory or solving method is unclear. I am a cum laude Aerospace Engineering graduate from TU Delft and have helped other pupils with their problems since 2017. With my calm and stepwise explanation, a second alternative view of the solution procedure is given, which is often what is missing. I tutor a variety of math and physics courses on both secondary and high school levels, but also at a scientific bachelor level. These can either be theory/exercise-based, but also exam preparation.

Hi, I'm Darioush! I'm a Computer Science student at Tbilisi State University (English-track program), based right here in Tbilisi.

Science has been my world since high school — I won a bronze medal at the Iranian National Astronomy Olympiad, competing against thousands of students nationwide. That competitive background gave me something most tutors don't have: I don't just know the textbook answer, I know why it's the answer, and how to break it down so it actually clicks.

I teach Physics and Mathematics from middle school through high school level, including exam prep and olympiad-style problem solving. I love bringing in real astronomy examples to make abstract concepts feel tangible — physics is just astronomy that hasn't looked up yet.

My teaching style: build intuition first, then speed. No memorizing formulas without understanding where they come from. Whether you're catching up, aiming for top grades, or prepping for a competition, I'll adapt to your pace and goals.

Fluent in English, lessons available in person in Tbilisi or online.

Let's make science make sense. 🚀

Hi, my name is Federica and I am an astrophysicist. I obtained my PhD from ETH Zürich and, for over ten years, I have been working in international research teams, contributing to space missions such as ESA Euclid and NASA Roman, and collaborating with scientists from all over the world.

For more than ten years, I have also been active in teaching, tutoring and science communication. In my teaching approach, I consider it essential to listen to the student, understand their needs, and identify the way they reason and learn best. This is key to creating a truly personalised learning path that motivates them to engage with the subject and gradually take on more advanced learning challenges.

I helped several students to strengthen the foundations, identify strategic points early, and progressively work towards more advanced problem-solving and exam preparation.

I do not believe in a standard “one-to-many” lesson, but rather in a learning path designed to genuinely consolidate the student’s knowledge, help them become progressively more independent, and make them aware of the practical and interdisciplinary applications that a particular subject can have in their academic journey.

I am fluent in Italian and English, and I am currently strengthening my knowledge of French. Thank you for your attention.
