In this video, I introduce the Nernst Equation and explain how it can be used to calculate the equilibrium potential of an ion (with sample calculation). Additionally, I discuss the significance of the equilibrium potential and its role in determining net ionic movement.

Not every teacher can master the art of explaining complicated topics so easily... The fact that you did and you thought of posting it online is wonderful.. I wish you would keep publishing videos like this... We really need more teachers like you...

i'm pissed that a free youtube video is better than professors that I paid ten of thousand of dollars to attend.

It's amazing to think how a handful of benevolent teachers like you sir can profoundly influence millions of students' education.

Can you explain how the constants end up 61.5? No matter what I do, I can not seem to get that. When I multiply RxT and then divide by F I get... ((8.3)(310.3))/96500=0.026689

Thank you so much for this video! Just started my neurophysiology course and was asked about the Nernst equation. This was so thorough and I love the example you provided!

i am confused . when you calculatetd the equilibrium you found it -80mV and then you said the batter has to be >+80 why is it plus and what do we do when we find a positive equilibrium

Thank you so much. The formula in the current guyton still uses the negative version this really made it clear to me now.

I need to know about the Nernst equation from a chemical perspective. Yet this video has shown me so much detail and easy explanation that I couldn't understand with chemical videos. I love when the sciences mix, coexist and help each other. Thanks for the video

This video is very helpful for me! My teacher explained this to me twice and I couldn't wrap my head around it. The visual representation is what I needed! Thank you!

I was asked this question during a physiology lecture and I got it wrong and none of my classmate could rescue me. Thanks for this wonderful , short video yet to the point!!

Thank you so much! I was so stuck on converting ln to log so I could never get the right mV. I finally understand this. You've been a great help!

You explained it amazingly (in a combination with the next video "the membrane potential")!!! Thank you sir!!
