In a conductor,$4$ coulombs of charge flows for $2$ seconds. The value of electric current will be:

“In lightning in the sky,there is a steady flow of charge”. -True or False?

Electric current has both magnitude and direction. It is a

In conductors,in the absence of an electric field,although electrons are in motion,why is no current formed?

The current in a conductor varies with time $t$ as $I = 2t + 3t^2$,where $I$ is in ampere and $t$ is in seconds. The electric charge flowing through a section of the conductor during $t = 2 \, s$ to $t = 3 \, s$ is ............. $C$.

The current flowing through a wire varies with time according to the formula $I = 3t^2 + 2t + 5$. The total charge passing through a cross-section of the wire in the interval from $t = 0$ to $t = 2$ seconds is ........... $C$.
