Define the electric current in terms of electric charge. Mention its practical unit of measurement. A charge of 4.8 C is transfered through the filament of an electric bulb in 30 s. (i) How many electrons are transfered? (ii) How many protons are transfered? (iii) What will be the reading of an ammeter connected in series with the bulb?

Answer:
Explanation:
An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge
Unit : ammeter
I=Q×t
=4.8×3
=144 A
No electrons = total charge / charge of an electron
4.8/1.6× 10^19
= 3×10^19
Sorry for the partial answer
