Question

(i) A current of 1 A flows in a series circuit
having an electric lamp and a conductor of
52 when connected to a 10 V battery.
Calculate the resistance of the electric
lamp.
(ii) Now, if a resistance of 10 S2 is connected in
parallel with this series combination, then
what change (if any) in current flowing
through 512 conductor and potential
difference across the lamp will take place?
Give reason.

Answer 1

Answer:

(I ).answer is 5ohm by using ohms law and also using equivalent resistance of circuit
