1. Translate the text. Переведитетекст:

The Electric Current

When a conductor joins two points of different potential, electricity flows from one to the other along the conductors until the potentials are equal. This process is very rapid, and with good conductors is completed in a fraction of a second. While it lasts, an electric current is said to flow from one point to the other. By convention, the direction of the current is said to be that from the higher to the lower potential, i.e. the direction in which positive charges would travel, but actually, owing to their much greater mobility, it is the negative electrons which move, and it is their motion which constitutes the current.
