## Description

The flow of electricity through a conductor, say a wire, is known as current. The unit of measure of current is ampere (A). The driving force for current is called the voltage, measured in volts (V).

The formula that connects current, resistance and voltage is often shown through Ohm’s Law. Other laws in electricity that help us solve problems are Kirchhoff’s current law and Kirchhoff’s Voltage law

**How I make my courses**

When I create content for lessons,I think deeply around the areas where students struggle and feel confused. My lessons tackle these parts in depth. Also, I believe visual representation of various ideas in physics makes a lot of impact. The lessons have visuals and animations that are thought through for faster learning and absorption of the subject

And most importantly, I make myself available to answer questions of students enrolled in my course

**My students (some are wonderful teachers too) wrote this to me**

Bobbie Smith: Amazing explanations, I really learned a lot. Thank you.

Satyam Jha: amazing!! i could not understand vector physics in my class but here it is very easy to understand Thanks!!

Csaba *(teacher):* I learned new ideas. *I’m looking to try them in my professional practice as a physics teacher*. Thanks! 🙂

Fernando P. Radaza: It help me a lot to understand better about physics of Work, Power & Energy.

Chamara Dilshan: it’s good, *explaining every small thing*,it’s good to start physics beginners

Onofrio : The lessons given by the teacher are very interesting! Excellent course!

Simaran: *Very deep understanding of the subject*

Shiva: Very knowledgeable and *sounds very nice and helpful*

Gallina: Excellent the lessons held by the teacher with *exhaustive explanations *and *well illustrated.* Well done course!

Smith: Great course.The *presentation is very clear*. Thank you.

Pawan Kumar: The way to teaching us is *amazing with all diagrams*

Samit This course has a lot of *good content and very well presented.* Thank you

Dani *(teacher): * It was concise and consequent. The *exercises were good exposed and explained.* Simply excellent. I promise, that i will use some ideas in my every day practice in my classroom. *I’m also teaching physics, but in Hungarian*. *I finished this course to improve my skills, first of all in interesting approaches, *and foreign language skills as well. *This course was exactly what I expected!*
