* A diode may be thought of as an electrical counterpart of a directional valve (\check valve"). * A check valve presents a small resistance if the pressure p >0, but blocks the ow (i.e., presents a large resistance) if p <0. * Similarly, a diode presents a small resistance in the forward direction and a large resistance in the reverse direction.
