Find the value of `i_(1)//I_(2)`in figure if (a)`R=0.1(Omega)` (b)`R=1(Omega)`(c)`R=10(Omega)`.Note from your answers that in order to get more current from a combination if two batteries they should be joined in parallel if the external resistance is small and in deries if the external resistance is large as compared to the internal resistances.
