Calculate the current flowing through a wire of resistance 5 Ω connected to a battery of potential difference 3 V.
As we know, V=IR⇒I=VR=35=0.6 A
Calculate the current flowing through a wire of resistance 7.5 Ω connected to a battery of potential difference 1.5 V.
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.
