Unformatted text preview: m / s 2 . 5. If two very long parallel wires one meter apart carry equal currents, the current in each is dened to be one Ampere [A] when the force per unit length on each wire is 2 10-7 [N/m]. 6. One Coulomb [C] is the charge owing through a cross-sectional area of a wire in one second when the current in the wire is one Ampere: C = A s. 7. = 4 10-7 N / A 2 . 8. = 8 . 85418782 10-12 C 2 / (N m 2 )....
