A coaxial cable consists of a solid center conducting wire and an outer coaxial cylindrical conductor. The space between the conductors and the outer insulation are made of a good insulating material e.g. neoprene. The figure below shows a cross section of such a cable. The current in the center wire is 2.47 A out of the page and the current in the outer conductor is 2.98 A into the page. If the distance a is 2.00 mm, determine the following.

Microscopic view of current

In physics, the term current is expressed as the rate of flow of electric charges across the area per unit time (I=q/t). It propagates along in the direction of the motion of positive charges. When the current is caused by the motion of electrons, the direction of the current is opposite to the flow.
