Short and informative video. Well done! :D

Thanks a ton!

Thanks a lot!

why is the potential difference(v) same in all resistors?

Even I would love to know that. i never understood why.

I still don't get why we can simplify by using the 1/v. I'm guessing this is because I'm missing some simple algebra logic, can anyone point me to where I might learn the logic of this exact simplification?
