Internal resistance of cells in parallel

  1. Oct 1, 2011 #1
    I know, as a matter of fact, that the equivalent resistance of three identical cells in parallel is equal to the internal resistance devided by 3. When we are concerning simply 3 equal resistors in parallel, I know that the outcome resistance is what. But when it comes to three cells with internal resistance, I don't understand why the emf is that of one cell and the resistance could be resolved so simply . Would anyone please give me a thorough explain on that? Much obliged!
