Equivalent circuit from the EIS plot in CH Instruments

#EIS #EISequivalentcircuit
In this video, I've tried to lay bare the basic technique to design the equivalent circuit from the EIS plot (Nyquist plot) using the CHI 660E software, provided with the CH Instruments Electrochemical Workstation.

Hey! I am now making videos using the Samsung Galaxy S6 tab. It's highly recommended to use. If you are a grad student you can have this pocket-friendly one. You can use a cool keyboard alongside, which will facilitate ease of working.

Dear sir,
Thank you so much for all your videos with CH instrument. those are really very useful. thanks again.

You said you can't just add circuits arbitrarily and you need explanation to your circuit. Then how can you explain your circuit??? Why do you put W or C or Q???

sir, how can we calculate the equivalent series resistance, charge transfer resistance, double-layer capacitance, etc.

Hello Ayan, thank you for this useful video but how can I get CHI 660E?

Sir can you plz help me in madink equivalent circuit of metasurfaces in CST?

hi, Iam Waleed I. Omara, I am from Iraq. I am working in corrosion laboratory, and make electrochemical experiments on ELECTROBANK potentiostat, and I want to add the EIS technique but I don't know how to simulate the equivalent circuit, and what is the benefit of it, could you advice me about this issue, thank you

[gabrielvinicius]

I performed the measurement and came home to treat the data. Then, guess what? To simulate and fit the data, the equipment must be connected 😵What a smart piece of s* !

Finally you haven't solved the circuit...
Fitting should be done systematically by observing nyquist you've done like you already know the circuit..you should play with 'n' value to reduce the errors, you're only doing automic fit, next to automatic fit there is option where you can play with component values and can reduce the errors.

thanks you very much for this video..pls give your email id..

"You have to change the circuit elements and justifg why you made this change""!!!

I am basically watching this vedio to know how to chose the circuit, how to nodify it and how fo justify the circuit design !!!
