Question

A current of 1 ampere flows in a series circuit containing an electric lamp and a conductor of 5 when connected to a 10 V battery. Calculate the resistance of the electric lamp.

Now if a resistance of 10 is connected in parallel with this series combination, what change (if any) in current flowing through 5 conductor and potential difference across the lamp will take place? Give reason.​

Answer 1

Answer:

Thus, I A current will flow through 10Ω resistor and 1A will flow through the lamp and conductor of 5Ω resistance. Hence, there will be no change in current flowing through 5Ω conductor. Also, there will be no change in potential difference across the lamp.
