Charge carriers which are free to move constitute a free current density, which are given by expressions such as those in this section. Electric current is a coarse, average quantity that tells what is happening in an entire wire. At position r at time t, the distribution of charge flowing is described by the current density: where Web10 jun. 2024 · 420 subscribers Subscribe 3.5K views 1 year ago This video presents the different methods of providing excitation to a coil such as defining current, current …
