NettetA diode is a device that allows current to flow in one direction but not in the reverse direction. Its circuit symbol consists of a triangle pointing in the direction that current isallowed to flow with a line at the point, inside a circle. Diodes are useful for stopping current flowing in the "wrong" direction.
