Oersted discovered that a compass needle deflects near a current-carrying conductor, showing it exerts a force on the needle. In 1821, Faraday found that a current-carrying conductor also deflects in a magnetic field, indicating mutual forces between the
Several solutions are extant in the industry. One solution is to interpose a section of nickel wire cable in the conductor. Unfortunately, in order to have sufficient current carrying capacity, that is ampacity, such a nickel wire cable is typically quite stiff in practice. Another solution is ...
“Current-carrying line of load” means a series of current path (comprising circuit conductor or cable) between the load and a power source (positive pole and negative pole) In case of that there is a driving circuit as a load, a current path between the driving circuit and the power ...
