How does heat make a memory wire straighten?
Thank you!
I love learning things about this type of stuff!!
thank you!
we should measure electricty in space, then run tests to see who can live there and if life is possible dispite the oxygen levels
how can we implement this in new inventions
Interesting and cool episode.
this was an epic episode
Very nice video!
nice video!
This was cool, entertaining, amazing, the best thing ever, the best video! the intro to everything
Learning about measuring electricity is so interesting!
So cool!
I wonder how different elements could change the electricity field.
So cool!
How did they find out you can measure electricity?
thank you
Thank you for this amazing video about electricity!
I love this video this video! Even though I am not an Acellus student, I found out from one of friends. I love watching these video’s every Wednesday. THANK YOU ACELLUS!!!
Awesome video
awesome video
It was cool to learn about how the computer mouse was invented and how it impacted modern day computers. Learning to measure electricity with multimeters was super interesting.
This was a very interesting video.
Amazing video!
Very cool
such an interesting video 🙂
Electricity is so powerful!
I enjoyed learning more about Multi- Meters with my Grandfather working on electricity work.
It’s crazy the amount of electricity humans can produce.
Electricity is one of my favorite things to learn about!
WOW
wow!!
its so cool how we can measure electricity
so cool my mom was an electrician
r-51 was very interesting lol!
How can a memory wire learn a position? Why does heat make it straighten?
awesome
This was an amazing video! Measuring electricity? Producing only a bit of what a lightning bolt can? It truly is fascinating how the world works.
This was an interesting watch.
Thank you for all the classes.
This is my second time coming back to this video! it’s so interesting
electricity is so interesting
Super cool lesson
I really think that we need the multi meter in the store.
A purple multimeter would look cool!
I wasnt aware you could measure electricity! Thats so interesting.
I enjoy learning about electricity!!
Technology is so amazing!
Learning about electricity is the coolest! Thanks
I learned a lot today
These videos are so inspiring
What are some mistakes to avoid when measuring electricity?
I love the science live always helps me learn something new!
Electricity is so interesting!
The Pajet cardboard cutout makes me laugh!
I always love Science Live! I have learned so much. Great video!
Loved learning about electricty and currents! Learned a lot. Thank you!
I learned a lot about electricity in this video. Also, way to go Charlie!
R-51 is so funny!🤣 I love these videos!
Resistance and Multimeters – My mom said she learned more from this video than she did in school about electricity and currents. My mom is your biggest fan.
REDDDDDDD PLEASEEEE
🥰
Thank you! learned a lot
My Dad was just using a multimeter the other day when he was working on the house.
It’s crazy the amount of electricity humans can produce so far yet, we’re at only a fraction of the power a lightning bolt makes with normal appliances.
I did not know you could measure electricity, super cool!
Love it 😁
I learned a lot watching this video.
The fact that electricity can be measured opens up endless possibilities of scientific research! The lengths we can reach through science are truly astonishing.
These videos are the best!
I really enjoyed Tobias’ talk regarding Douglas Engelbert and the invention of the original mouse. Who knew how important the mouse would become for computer technology
R-51 is awesome! And I wish I had a multimeter
“Resistor” HELP!! XDDD
Hi! I watched this live from North Carolina. I really enjoyed the live! I absolutely love how everything is about science and also loved learning more ab measuring electricity, etc. Thank you!!
love learning something new everyday!
Love to have that book
Where do you think computers will be in the next 25 years?
I never knew you could measure electricity!
I love r-51!!
Thank you!
Love new information and I really dislike the change of daylight saving time.
Nice! Learning about measuring electricity was pretty interesting.
Measuring electricity is awesome!
This is so neat!!
I liked r-51 a lot!
R-51 is goofy
Yes please put mutimeters on the store in a black and gray color
I didn’t even know measuring electricity was a thing thank you!
Can we get a book like that??
so cool loved learning about Resistance and Multimeters
Amazing live as usual
Thank you!!
This is so cool! Also that end bit was really meaningful
ha so funny. I love R-51
I love how multimeters work
I really liked learning how to measure electricity. I learned something new.
I love R-51
I love how the original mouse actually looked a lot more like a mouse!
Learning about how to measure electricity is really cool!
This was a great episode! I do think y’all should include a multimeter in the store, it seems like it’d be fun to play around with.
I love the store! thank you for making it!
R-51 is so funny!
I love a pink mulitmeter in gold store
I had a multimeter I only used it for alternating current.
Thank you for educating me on the many uses of the multimeter and resisters.
Whats you guys favorite school subject? (Besides science)
I LOVE YOU DR ROGER BILLING
It was very cool to hear about 4 new planets circling Barnard’s star, how big are they?
Thankful for Acellus and being able to learn about technology
I would love to see pink mulitmeters in the gold store. I love Todd Edmond and would love to see him in more courses! I love science live!
I love how the mouse was invented.
Learning about Ohm’s Law and how electricity works is so interesting
multimeters are fascinating!!!
I really enjoyed learning how to measure electricity!
Did Elon Musk get the name Tesla after the guy named Tesla?
Love learning about electricity
Wow this episode was great
Always love breakthrough moments in science
THIS IS SO COOL
I’m so thankful for Acellus:)
One of my favorite videos yet! thank you for sharing this.
I was diagnosed with ADHD.
I really don’t like to sit still. This school helps me not have to sit down for very long. And I like school now. This will be my third week at Acellus.
Dr. B is such a great salesman. He made that multimeter sound like the most fun thing of all; And yes I think you guys should put some In the Acellus Store maybe in blue.
I love the ai bit 😂
With one questions I have I was wondering if there would be more in depth videos further explaining it . For example what factors would be needed to cause the resistance in the conductor.
My dad uses multimeters in his work
I did not understand how voltage was measured before, great Science Live
This is good information to have because almost everything has batteries now.
Tobias has always been an awesome segment but this one was super interesting.
I couldn’t imagine having to use arrow keys to move around my cursor so glad we have computer mice
Wow this science live was very informative and i really enjoyed it!
Woah, I didn’t know we could measure electricity!
Electricity Is really cool!
Cool video.
where do you find muscle wire?
I love Science Live videos!
Thankful for the video lives
Thank you Dr. Roger Billings for this program.
Love Science Live
Love Acellus
Jingle bells was funny
Are multimeters able to detect electromagnetic fields from a light installation?
This is literally my favorite episode of science life. I’m hopefully going to be an electrician someday!!⚡️⚡️
I would like to have a red one in the store. This was a great video!
Yes, please put the multimeters in the Gold Store – purple or red
Acellus is the best!
Thank you for this Episode of Science live, Second week on Acellus so far!
Watching from connecticut
We love acellus, My son har soared with his learning skills since joining.
Wow! i really liked this one! so interesting!
I’ve always wondered how electricity works, and I do now.
Nice watch Dr.B!
That is amazing, i love watching science live, Roger billing and Pajet are remarkble when they are together
this one was quite mind boggling!
Pretty cool
Can you put a purple multimeter in the store.
Do they know why some resistors are more tolerant than others?
i wonder what the most amount of voltage ever pushed through any given conductor was.
what factors affect the resistance of a conductor?
I really loved this one!
I have to use a mouse with my computer. I cant imagine it any other way.
This is so amazing!
I want my own star now
why should you make sure the circuit is powered off?
I love science live q(≧▽≦q)
i love acellus [:
I wish I could be there and see how science live do it.
I love watching science live!
this Wednesday was one of my favorites :}
I like the live videos.we can learned a lot .My son like these videos and how they explained with experiments when he heard those videos afterwards he likes science and he told me that mom now I want to become a scientist .He loves to doing experiments a different things .✌
What is a multimeter?
Wow! I had no clue that that’s house mice for computers came to be.
Love Acellus
It was pretty fun with DR. Roger Billings
Acellus has really help me, and other friends and family! This school helps many people, including me! The fact that this community is willing to help any and all kids like me! Keep up what you’re doing Acellus!! Thank you!! Congrats to Charile!!
I love daylight savings time! Lighter longer
this is awesome!!!!!!
