I really enjoyed studying Ohm’s law in physics class!
Amazing and educational video!
Learning new things and having new strategies every time I see an episode
Its very important to use teamwork because it just brings a lot of positives and helps I’m very happy this episode was amazing!
LOVE the video
Pajet Monet is so pretty! Great topic to learn about. ( I wont be smoking anytime soon, don’t worry R51 lol)
I had never heard of Ohm’s Law before this lesson.
It’s truly amazing how Ohms Law is a straightforward relationship but turns into a gateway to understanding and manipulating the forces that holds our world. Thank you so much for telling us this amazing information.
How did they know it had carbon in it?
This is probably my fav so far!
this was a good episode
Interesting and funny
who created the ohms law?
Never really knew of Ohm’s Law until this.
wow this is super interesting!
this was so cool to learn about!!
I had heard of Ohm’s Law but never actually learned about it. Thanks for teaching me the meaning!!
Who created the ohms law.
I WANT TO THANK ACELLUS FOR HELPING ME AND MY FRIENDS AND YES THAT INCLUDES THE ONES I AM TALKING TO NOW
How interesting!!
This is awesome!!
this is super interesting!!!
i remember hearing about this law at my old school before i came to acellus and it was so confusing until i watched this video!
nice video
I wish I knew on what episodes I’ve commented on already, as always r51 is quite funny.
Where can I get the camera that you showed me?
Very funny loved the video
nice video!
Knowing the basics of electricity is a very necessary skill.

I’m super exited to go to sedentary school I’ve wanted to join USAFA for years and winning that science fair would look amazing to the school!!!!!!!!!!!!!!!!!!!!!
You are every good at explaining Ohm’s law!
I really liked r-51 in that one.
You explain this very well
For some reason Ohm’s Law was so confusing before this!
I remember learning Ohm’s law in physics class on Acellus!
This episode sparked in me the desire to comprehend how electricity works and how to do it correctly. I appreciate Dr. Billings’s time in creating this opportunity of all students.
I had no clue Ohm’s law was a thing until you!
Never really understood Ohm’s Law clearly until this!
You explained Ohm’s law very good.
Electricity is cool when you can see the ways it works.
Thank You for teaching us Ohms law. This really helped me understand circuits better.
Thank you for teaching me about Ohms Law!
Batteries have come a long way.
ohm’s law is so interesting.
It’s smoking🤣LOL!!!!!!!!!!!!
Thank you!!!!! Your teaching was easy to understand.
I learned a lot about Ohm’s Law. Very interesting.
I like how you compared the flow of electricity to the flow of water. It helped me understand a lot better.
Thank you for explaining Ohms law
R 51 is so funny!!
I’m so glad we can spend the coins now i will be saving up for a Leatherman jacket it looks so cool!
Lady paget is a great teacher!
Science laws are so interesting, and I also love magic!
This was a great episode! It’s great to know I will be invested and learn many cool things every video. Now I fully understand Ohm’s Law, thank you Acellus!
I love how in every video Dr. B has visuals to under stand the videos more.
I have not heard of some of these things, this was interesting.
I never knew how many things batteries can be used for. He does a great job at breaking down so it is easier to undertsand.
Learning about the lithium battery was interesting, and I learned a lot!
The Ohm’s law formula is E (voltage) = IR ! Fun.
The way he explains it makes it to where I can understand it
wow
Wow how interesting, I didn’t know that!
always a pleasure watching these , the way you guys can bring teaching to such life for homeschool student is so appreciated. Very fun way to learn about Ohms law .
Its really helpful with the examples shown, interesting episode!
I never knew about ohms law until this
I never knew that John Goodenough and two others were the ones that created the lithium-ion battery.
learning about electricity is so fun!
Thank you for this video.
fun
Very interesting. Learning something new every video
I really liked learning about lithium battery and how it came to be today, Great episode!
I really liked their explanation on ohm’s law it was easy to understand and interesting to learn about.
This taught me so much about Ohms law!
Ohm’s Law is so interesting!
Batteries can be used for a lot of things VERY COOL
Ohm’s Law is really interesting, these Science Lives are always awesome!
its so much easier to learn these things with visuals and having someone explain the whole process!
In my old school it was always really hard for me to understand anything science related because they weren’t as hands on, so I love that acellus is!
This was an amazing way to explain Ohms law!
Dr. Tobias had a great explanation for the lithium battery. They are working to make a lithium battery to fly an airplane long distance.
Does the Amp for a guitar get its name from the measurement of how many electrons are flowing or is it a coincidence?
If we didn’t have electricity today, what do you think our world would be like?
This is awesome!
Electricity is cool!
This is the way I understand Ohm’s Law, is like water flowing through a pipe:
Voltage (V) is like the water pressure pushing the water through the pipe.
Current (I) is like the amount of water flowing through the pipe.
Resistance (R) is like the size of the pipe—if the pipe is narrow, it’s harder for the water to flow (more resistance).
I really liked Dr. Tobias’ explanation about the Lithium Ion Battery. I also really liked Dr. B’s explanation of OHM’s law. I learned a lot today.
I love electricity and I really need it.
This was great!
My dad works in construction I had a very good conversation about ohms law with him.
Electricity was so hard to follow and understand, but the way you guys explained it, made me understand it way better.
My question is, How did Mr.Billings know how much pressure would pop a tire? hahahaha.
Electricity is always so cool to learn about!
Ohm’s Law is really a interesting study.
This was really great. Not sure why we can’t leave the comment. this is our 2nd try.
I enjoyed this episode. I helped my dad check the ohms on our air conditioner one time.
I really enjoyed learning about Ohm’s Law.
I enjoyed this video; my dad is an electrician and talks about ohms sometimes.
ohms law is really neat. it was easy to foolow with how you explained it.
I’ve learned about this in one of my classes thanks for expanding my knowledge
Wow, i really like the diagrams drawn, they are super cool and helpful in understanding
Can a fella tell me when (yk what i mean, the number label) the first episode including r-51 aired? Been tryin to find it but it keeps goin’!
I always love and enjoy watching these shows. Thank you !
I appreciate this lesson of ohm’s law it’s fascinating how voltage current and resistance are all connected just like how increasing resistance lowers the current in a circuit.
Science is cool
Learn some new every week thanks to these episodes
Everyone on his show retains a happy and upbeat vibe. They all do a good job of keeping the viewer engaged.
Awesome show! I love the information.
I really enjoyed learning about ohm’s law and batteries today!
How do remote control work?
I’ve never heard of Ohm’s law very interesting, and I enjoyed learning about it.
I found Ohms law to be very interesting how everything worked together to form a electrical circuit.
ohm’s law is interesting.
That’s really cool but why
My favorite part of this video was Tobias talking about the battery and hoe its system worked, which had used salt water.
Dr.Tobias is so funny!
Wow, you can always expect to learn something new on science live!!
Wow, always learn something new on science live
It was fun learning about this law because I had never heard of it before.

Ohm’s Law is named after Georg Simon Ohm, the German born physicist.
i like to learn more about OHMs law
Omg I never knew there was a specific symbol for a battery!
Can there be two currents along one path?
where did the word voltage originate from?
Ohms Law is actually pretty cool!!
Love learning about new things.
