ur video is nice but i am facing problem that current at y=axis is in 10exp-7 range and mostly in vidos and reported data it is in 10exp-4 range as is in ur case, m i doing mistake in some conversion or what? please guide

[@BiplabKDeka]

Great explanation. really helpful. Plz make videos on how to calculate Energy and power density with unit conversion.

[@aadilkhan9196]

A.O.A Really good one and nicely explained.But I have an objection. I hope you will try to resolve it. During surface area calculation we should use area within the CV loop , actually you divide the equation by 2 to get that area (area within the CV loop) .But in example solution you have determined that area (within the loop) then you should not divide the equatiuon by 2.

[@nanoworld6122]

This formula is used for both, i.e. 2 electrodes as well as 3 electrodes electrochemical work station data. In the case of the 2 electrode system, if we considered the electrodes are symmetric (ideally) then we should not divide it by 2 ( we considered it is already divided). I performed my CV characterization in 3 electrodes electrochemical work station ( As I mention it in my video), that's why I divide it by 2.

[@sharafpc786]

What does the capacitance during discharge exactly means? Little confused here.. isn't it the device capacitance? Why need to subtract it from charging capacitance to get the device capacitance?

[@9847356129]

calculate diffusive and capacitive contributions for electrode material can you do video on this

[@Tsastm]

Sir what is the interpretation of the area of the CV curve? I mean if it's large what does it say and vice-versa

[@jagadeswarchandra4951]

the integration has an error , the v in k is not included

[@ruchindagooneratne7684]

Love all the vids! I do have a question with regard to the final equation. Since the absolute area was used, shouldn't eq (6) be used instead of (10)? Meaning, that the specific capacitance doesnt need to be divided by 2? Thanks!

[@muhammadadeelasghar3236]

Good observation. I've explained it in my comment.

[@troi818]

@@muhammadadeelasghar3236 Can you explain agian why you did not use equation 6 since the area from origin is already absolute area?

[@uthmanalli4636]

Can we get an answer to this question, please? I've been curious about it. They both give different values of area, and I've seen different videos where integrate-absolute area has been used instead of polygon-absolute area, Why is this?

[@kirannargatti]

Really helpful and great explanation. But one thing is not clear, in case of 3 electrode system if we consider absolute area from origin software, then the capacitance equation will be A/2mk(v2-v1) or A/mk(v2-v1)? and in given example, final answer 33.89 is correct or it should be 67.78?

[@guadalupesuarez5002]

I have a doubt, the potential is in Volts not mV such as appear in the original file? and the rate scan in mV?

[@nanoworld6122]

yes, the potential is in Volts and the scan rate in in mV

[@adillasasongko7227]

Why it divided by two?

[@navinmech540]

How A2 is just negative of A1? A2 magnitude is lesser than A1.

[@ManSingh-mw1il]

i have one query. you have area in (AV), mass in (g), scan rate in (mV/s), potential window in (V) so how do you got capacitance in F/g. I think area should be in (mAV)

[@nanoworld6122]

Please re-watch this video, and note everything in your note book and then re-think about it.

[@ManSingh-mw1il]

@@nanoworld6122 yes sir, i got it now, you have converted scan rate into V/s during calculation. Thank you for replying sir.

[@shelkaze6242]

thanks for tutorial, much helpful.lol

[@speedstar6140]

Don't you think that the unit of scan rate should also be V/s instead of mV/s that you are using while calculating Cp in excel sheet. Since 1 F is equal to 1 A.s/V

[@nanoworld6122]

I think you did not watch it carefully. When putting formula, I multiply it with 10^-3. This means I already used V/s for the rate. Please re-watch
