Why does the current becomes constant when n number of identical cells having internal resistance r are connected in serie and are FUSED together ? Does the current becomes I =E/ R ( where R is the external resistance) or does the current becomes I=E/r ( where r is the internal resistance) . Which of the resistance becomes negligible? |
