## Main Question or Discussion Point

Suppose we have any simple circuit and we are giving it a voltage of 5V, then I cannot understand what is the role of current in that.

I know current is the flow of electrons in it, but, what really is the difference between the supplying of voltage and the supplying of current ? !

I just get mixed up with the practical purposes of current and voltage
