Question

(a) define the term one coulomb.(b) state the relationship b/w the electric current, the charge moving through a conductor and the time of flow.calculate the charge passing through an electric bulb in 30 minutes if the value of current is 300 mA.

Answer 1

(i) Define the term ‘coulomb’. 

(ii) State the relationship between the electric current, the charge moving through a conductor and the time of flow. Calculate the charge passing through an electric bulb in 20 minutes if the value of current is 200 mA.
