A current of 1 A flows in a series circuit containing an electric lamp and a conductor

\huge \fbox \blue{Question}

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