Magnetic field of circular wire
Generated at the center of a circular wire by the electric current, related to the electric current and the distance from the wire to center of the circle.
Shockley ideal diode equation
In electronics, a diode is a two-terminal electronic component with asymmetric conductance; it has low (ideally zero) resistance to current in one
