Intro to Ohm's Law & Deeper Look at Voltage in Circuits

In this video, we introduce you to the basics of Ohm's Law, one of the most fundamental principles in electrical engineering. Ohm's Law describes the relationship between voltage, current, and resistance in an electrical circuit.

We start by defining each of these terms and explaining how they relate to one another. We then move on to explore Ohm's Law in more detail, discussing how it can be used to calculate voltage, current, and resistance in a circuit.

Along the way, we use real-world examples and interactive animations to illustrate these concepts and make them easier to understand. We also discuss some common applications of Ohm's Law in electrical engineering, such as designing circuits and selecting appropriate components.

By the end of this video, you will have a solid understanding of the basics of Ohm's Law and how it applies to electrical circuits. Whether you're a student just starting out in electrical engineering or a professional looking to brush up on your skills, this video is the perfect introduction to this essential topic.

I've been wondering about different battery sizes for years. Thanks for the good explanation.

Professor Math and Science Tutor, thank you for a practical Introduction to Ohm's Law and a Deeper look at Voltage in Circuits. The measurements of Currents/Voltage/Amps using a Digital Volt Ohm meter increases my overall knowledge and understanding of Ohm's Law. This is an error free video/lecture on YouTube TV with the Math and Science Tutor.

Sir I don't have words to explain the beauty of your explanation of these lessons, you are the best, you are the best of the best, 💖🥰, we all love you respected Sir,

[amitavachakraborty]

He has intense enthusiasm to make us understand, great job thanks.

[ottomendez]

It could not be any more interesting learning, you bring knowledge to remote and every where. THANK!!.

[nasserkaouk]

Loved the way you are teaching this hard to understand subject

[walterwelch]

When I first learned electronics w e were taught the volts were E or Electromotive force, the I or Intensity or current and R for Resistance. The ohms law was E=IE and P for power in Watts was calculated as P= IE. But not pi which 3.18. Love your channel. Have a great day.

Thank you Sir for making these pure gold videos! You are an underrated teacher!

[firstdayonline]

Exscellent teacher! Really, really thank you! You are one of the best!

[eduardmeyer]

Thank you very much for your commitment! Happy new year!🎉

[wilkyclergeot]

Thank you so much incredible teacher!!!

[jomarv]

thanks a lot of your video sir, , very impormative about electrical course..

[Cristianxrivera]

Appreciate you for sharing your knowledge blessings 🙏🏽

[roncaruso]

This reminds me of my electronics traing back in the 1990's.

[rajlaman]

love this mix of theory and practical examples .. it really helps in building intuitive understanding of concepts presented

[michaelphillips-nxs]

IR in the battery " internal resistance " well, you just said it! 🎉

[Joabfilandus]

Wow, thanks tr. Getting the whole concept here really ❤❤🎉🎉

Now I understand why I cannot start a car with 8 1.5 Volt AA batteries. The voltage drop would result in a much lower 'real' voltage, and therefore significantly lower amperage (linear). And thank you for your teachings. Honest, un-biased, poignant.

[hemrajue]

I think voltage is a form of potential energy.
