Question

Define electric current. A current of $1A$ is drawn by a filament of an electric bulb for $30$ second. Find the amount of electric charge that flows through the circuit.

Answer 1

Electric current is defined as the rate of flow of negative charges of the conductor. In other words, the continuous flow of electrons in an electric circuit is called an electric current.The conducting material consists a large number of free electrons which move from one atom to the other at random.

$I=\frac{q}{t}⟹q=It⟹q=1\times 30=30C$
