YOU ARE A GOD OF PHYSICS. PLEASE ADD THIS TO UR FAVS AND LIKE IT SO EVERYONE CAN SEE IT!!

[soumyasayujya]

:) cool explanation SIR!!....

[Master1906]

Wow! Great teacher.

[gorillamanstan123]

This is the Billy Mays of science

[DemonX99]

Great video, thanks!

[aguuled]

If I had this guy as a teacher, I would have kicked Einstein's behind.

[chazmazzer]

Thank you. Thankyouthankyouthankyouthanky­outhankyou!

[Flextaa]

You are awesome I didn't even need to play it twice.

[Daniel2009Guitar]

His enthusiasm makes me so enthusiatic about Physics lmao

[TheBadbowman]

Thx so much I understand this a lot more

[MrGregorykins]

you are awesome

[onexism]

you saved my life!!!!!!!!!!!!! my chem midterm is today. thank you so much

[MickeyJIC8]

i'm lost... In the second diagram when he was saying that we turn up the voltage until there is not current, how is that possible? okay so you turn up the voltage then the current is suppose to move from positive charge to the negative so the positive side is suppose to gain more energy to carry the electrons to the other side right? and if so then there's no way for the positive side to lost energy then...idk someone please help me to sort things out.

@MickeyJIC8 electrons move opp. to the direction of current...

[MoraHeadhunter]

@MickeyJIC8 electrons move opposite to the direction of the current so the battery is repelling any electron from jumping through. Thus stopping voltage.

Thank you! really appreciate people like you who make physics interesting and easy to understand, and your passion for the subject is infectious :)

[samin33]

Thank you very much

[Alcuham]

Excellent explanation - so much better than my physics "teacher"

[crysty200718]

this guy is smart

[theyasin33]

What do you mean increase the intensity of light? Do you mean increasing the wavelength?? ANYBODY?

[sufjanfan92]

@theyasin33

how many photons per second hot the metal 

[theyasin33]

@sufjanfan92 thanks!

[gabis333333]

@theyasin33 intensity is pretty much referring to brightness or luminosity. basically when a light is more intense or brighter, their is simply more light being shined in total. ie a dim incandescent bulb vs a bright halogen bulb. This does not mean increasing the wavelength. It is just more light overall, but not more energy per bit of light.

[theyasin33]

@gabis333333 thank you very much dear friend

[sandslash123]

10/10 Perfect explanation

[BrmoodaEvil]

i wish if this theacher is mine

[rsotbairnfire]

Thank you for the explanation! It was more helpful than any other I've found on Youtube so far.

[strawberrytoot]

Why can't all teachers be this enthusiastic?

[NinjaRixks1]

@strawberrytoot

mine is xD

Makes physics so much more fun

[kyleisreallycool]

@strawberrytoot because they don't all do cocaine

[BigWapiti]

@strawberrytoot Because this guy isn't staring at all your blank careless faces like your teachers have to. Show enthusiasm in class and maybe your teachers will be able to express their own enthusiasms (like this guy). =)
