I am really confused with the above problem.

Each side represents a resistance R. How should I calculate resistance in case of infinite resistances.

    This is a classic puzzle. If you google 'infinite resistor grid' you will find many detailed answers – Electro_Woog May 17 '18 at 07:37

    Ah. The infamous [xkcd 356](https://xkcd.com/356/) problem. Here's a way to numerically approximate it: [VB.NET program to solve any finite resistor grid](https://electronics.stackexchange.com/questions/342340/how-do-you-determine-the-effective-resistance-of-a-finite-grid-of-resistors/342358#342358). Google hits this one [every time](http://www.mathpages.com/home/kmath668/kmath668.htm) for some math work. – jonk May 17 '18 at 07:38
  • @Electro_Woog, I read somewhere that it is impossible to solve this. Is this true? – Nikhil Kashyap May 17 '18 at 08:04

    *impossible to solve this* If you want an **exact** answer then indeed you will probably not get it. As more resistors are added the influence of these extra resistors on the answer will be smaller and smaller. So in my opinion the answer is really a limit function. – Bimpelrekkie May 17 '18 at 08:26
