The combined resistance of two conductors in series is 1Ω. If the conductance of one conductor is 1.1 siemen, the conductance of the other conductor in siemen is
A current of 1 ampere 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 conductors and the potential difference across the lamp will take place? Give reason.
