Plastic is a bad conductor of electricity, then how does it create a magnetic field around it?
Question 26 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.
