Define SI unit of current in terms of the force between two parallel current carrying conductors. (b) Two long straight parallel conductors carrying steady currents I_(a)andI_(b) along the same direction are separated by a distance d. How does one explain the force of attraction between them ? If a third conductor carrying a current I_(c) in the opposite direction is placed just in the middle of these conductors , find the resultant force acting on the third conductor.

Using the concept of force between two infinitely long parallel current carrying conductors, define one ampere of current between two infinitely long parallel current carrying conductors, define one ampere of current.
