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 !!! : ))

[2012-02-02 02:36:55] mathtutordvd - Its doubtful. It ...Its doubtful. It does produce electricity, but very little.
[2012-02-01 19:08:52] lrose30198 - Could you hook this ...Could you hook this up to a device with a dead re-chargeable battery and charge the battery? Say I have a more complex calculator with a re-chargeable battery that is dead but I've lost the charger cord. Could I hook up (4 or 5) the lemons in series via the aux battery compartment's + and - terminals & re-charge the internal battery?

[2012-01-29 18:19:28] CosmicCaprice - thank you Jason! i ...thank you Jason! i learned something new. now i know how batteries produce electricity.
[2012-01-29 16:18:35] mathtutordvd - Yep, other citrus ...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!
[2012-01-29 16:17:55] mathtutordvd - Awesome comment! ...Awesome comment! Me too actually! I got interested in science by watching shows like this on TV!
[2012-01-29 15:41:38] balikesier - Everything started ...Everything started with these kind of videos and books. Now I have PhD in Electrical engineering ..so watch out yourself.
[2012-01-29 03:37:01] SplitSniper7 - Can other citrus ...Can other citrus type fruits produce stronger results? Or maybe even metals?
[2012-01-07 05:59:30] CornOnTheCobIIV - i learned what ...i learned what voltage means

[2011-11-05 22:17:14] micfo4myneeds - I'm Studying ...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
[2011-11-04 22:09:19] mathtutordvd - Absolutely. My ...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!
[2011-11-04 16:12:51] tsameem - Hi man this video ...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?
[2011-11-04 13:44:37] mathtutordvd - I assure you, ...I assure you, everything you see in the video is 100% real! Try it yourself!
[2011-11-04 13:26:00] EngElecronics - you may have ...you may have injected the Lemon with elecetric battery to trick us
[2011-08-28 04:40:05] EpicHawk - What is the intro ...What is the intro music Jason ?
[2011-08-16 04:02:14] noblessus - Awesome video! ...Awesome video! Very interesting! Subscribed!
[2011-08-15 16:08:12] mathtutordvd - In general, its ...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!
[2011-08-15 10:03:23] SLEAZY808 - Thanks Jason! My ...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.
