(a) A current of `1 A` flows in a series curcuit containing an electric lamp and a conductor of `5 Omega` when connected to a `10 V` battery. Calculate the resistance of the electric lamp.  (b) Now if a resistance of `10 Omega` is connected in parallel with this series combination, what change (if any) in current flowing through `5 Omega` conductor and potential difference across the lamp will take place ? Give reason.
