The internal resistance of an accumulato...

The internal resistance of an accumulator battery of emf 6V is `10(Omega)`when it is fully discharged,As the battery gets charged up.its internal resistance decreases to `1(Omega)`The battery in its completely discharged state is connected to a charger which maintains a constant potential difference of 9 V.Find the current through the battery (a)just after the connections are made and (b) after a long time when it is completely charged.
