Learn how to build a simple battery out of a lemon and common household materials. You'll learn how to measure the voltage of this battery and how to connect them in series to power a calculator with lemons. You'll also learn exactly how this happens and how batteries in general work.
@CosmicCaprice Awesome! Glad you enjoyed it!
You are very good at explaining these principles. Thank you.
@mikepuc11 Thank you so much! Glad you like them!
THE SO MUCH FOR EXPLAINING THIS FOR MY SCINCE PROJECT
Thank you for help on my science project!!!!! :)
You are so welcome!
More videos like this please! I learned ALOT in just 15min! Thank You!
@SplitSniper7 Yep, other citrus fruits work! Anything with an acid inside actually works. In fact, even potatoes work :) There is a weak acid in those as well!
Hello!
I just love all your lessons !!!!! You are super teacher !!!!
Your probability & statistics got me top position in the finals ! I scored 45 out of 50 ! top in the class!
Right now studying Circuits ! But sir whatever, you are really an amazing teacher !!!!!
I just want to say Thank You from the bottom of my heart !!!
: ))
this is a great way to show my fourth graders how the batteries are form. Thank you so much.I also liked the comment from Christine Mullins
Hope you were able to solder the calculator leads back on afterwards!
Thanks so so much for showing me this,this helps me a lot for this
@balikesier Awesome comment! Me too actually! I got interested in science by watching shows like this on TV!
I agree, it's pretty darn impressive. I'm surprised this video doesn't have 4 or 5 million views.
Very informative and entertaining video. I enjoyed it to the max!
Respect from Dubai.
@SLEAZY808 In general, its usually 1 or 2 courses in chemistry, depending on the university. Definitely do not need to take organic chemistry as an EE or ME major. Thanks!
Jason, these videos are great!
love the background
You should of explain more what makes the penny ground? It also has zinc, right?
The penny has a copper outside and a zinc inside. The zinc of the penny doesn't come into contact with the lemon.
Why does the penny attracts the zinc electrons? Because it doesn't oxidize with lemon acid?
Hi man this video is great
I need Personal Guide from You
do u know any other websites provide more extensive Physics / Engineering Lectures ?
Do you know any other resoruces provide How-to make experiments and things like this ?
the math tutorials in ur site are helpful for engineers or useless?
What kind of zinc nails exactly
Awesome video! Very interesting! Subscribed!
THANK YOU !
I like it..but why did you used the yellow wire?
Can other citrus type fruits produce stronger results? Or maybe even metals?
Yup
sir please must it be a calvamise nail?
I have seen some energy drinks commercials which use the drink to power a bulb is it real? they claim the energy comes from the acids in the drink and if its true, is it safe to drink? im only a second grade student so please answer.
where can you buy dose yellow wires and the black and red wire please help i wana do this for the sceince fair project :(
can we use oranges too?
@lrose30198 Its doubtful. It does produce electricity, but very little.
How long will the battery last?
@EngElecronics I assure you, everything you see in the video is 100% real! Try it yourself!
Where do you get this stuff?
If you can make a battery out of lemon or potato, can you make one out of a tree? Or field of grass?
What is the intro music Jason ?
Holy crap i didn't know you could do that
where did you get the wires
yes
Hey do you think I can do lemon battery with wires
I'm Studying Mechanical Engineering at University
but im not very good at Mathematics
What courses u suggest me to purchase that be good with my Age '' 22 years old ''
all cours can work with Engineers ? cuz I feel that some of them are for High School only
Do you need the measure thing
whats a volt ? well it 's 1ooo,ooo million electrons in flow that = 1 volt its basic math and the lemon battery has a anode and a cathode like most other kinds made and sold thay dont last to long tho if you look at how its made we see its allso a acid diode has same parts for electrode now we can make a self powering transistor and it can be recharged to a point that its self run
awesome thanks... now i know what to do when the zombies steal all the batteries :)
I hate that this is backwards from what the atoms are actually doing. The zinc isn’t negative it’s more possible after losing electrons. I think electrical engineers got lazy somewhere along the way and just didn’t feel like dealing with negative numbers lol
What is the intro song?
in theory, if 100 lemons shown in the video are connected, can it power up a cell phone?
not reallty
Gabriel Quiros you have to use more like 1000
lemons
Connect 100 lemons in series you would have a voltage of about 75-80 volts. In theory, a mobile phone would be kindled, indeed, it would burn at this voltage, but the current that would occur with 100 lemons in series is low from the point of view of the absorption of the phone. You should do a test with a phone used to see the result ..
Electric Experiments Doing a rough calculation, using a mobile phone that works at 7-8 volts, should be connected in series to get 10 lemons 7-8 volts. Connected in parallel to these other 9 rows of 10 lemons in series. In this way, certainly the phone works well.
@mathtutordvd
Thanks Jason! My nephew will love this experiment. Reminds me of redox reactions back in general chemistry. I also have a question for you. How much knowledge in the chemistry subject is required in the field of electrical and mechanical engineering? I always wanted to ask that question because the engineers build the tools that are required for experiments. For example, we did an experiment on measuring H+ ions in a pH buffer solution with a digital pH meter.
Everything started with these kind of videos and books. Now I have PhD in Electrical engineering ..so watch out yourself.
Why do you always have to put on your safety googles
because when you cut the fruit the acid might go in your eyes
prolect is very onderful
Looks like he has a cat on his shoulders! Ha!

You don't need two lemons? Two nails would produce the same.
its simpler to explain that way i think
yes this video i usud to my science fair
Hay gorda. Sos traviesinga
Same
i learned what voltage means
Sometimes the simplest experiments can make you remember the most important of topics :D
thank you i am doing a science fair project and this was my idea
You ruined a perfectly good calculator. lol.
yay science
im going to do this for my science project
i hope this works
ur kewl
HEY!
I used nails but I didn't work
Can you send me a black belt
i'm not sure its true
I used pennies to power my calculator
@tsameem Absolutely. My website, MathTutorDVD(dot)com, contains an extensive physics and chemistry series. I also have an engineering level series on circuit analysis and plan more engineering courses in the future. Thanks!
WHO GETS LEMMONS
THAT IS SO STUPID
