- Two power lines run parallel for a distance of 283 m and are separated by a distance of 40.0 cm. If the current in each of the two lines is 115 A and if they run in opposite directions, determine the magnitude and direction of the force each wire exerts on the other.Let's take a current-carrying cable with a gradually narrowing cross-sectional area along the length of the wire so the wire turns into the shape of a very long, truncated cone. How does the drift speed (vd) vary along the length of the wire? It speeds up with the length or vd first increases and then goes down after it reaches to a critical value.or It slows down with the length of the cable or vd remains the same regardless the cross section of the cable.9.
