Any resistor, if you measure carefully, or for something less subtle:
a diode:
           |i *
           |  *
           | *
           | *        v
**********+*----------
           |
           |
           |
           |
A zener diode:
           |i *
           |  *
           | *
           | *        v
-----*****+*----------
      *    |
      *    |
      *    |
      *    |
