diode

Schematic representation and physical representation of a diode.

Schematic representation and physical representation of a diode. The schematic form shows an equilateral triangle with a line bisecting the triangle equally from one point to and through the middle of the opposing flat side. There is also a line perpendicular to the other line that also intersects the triangle at its bisected point. The cathode is represented by the side of the schematic with the line. The drawing of the physical form of the diode looks like a black resistor with only a single grey stripe on one side. The side with the stripe represents the cathode
