Non Ohmic Constant Voltage Drop "Resistor"

[Bret Cahill]

Most resisters follow ohm's law. The higher the current the greater the voltage drop.

Is there any passive device in electronics where the voltage drop is constant no matter the current?

Zener diode? ( over a limited current range.)

How do you build an amplifier out of one?

a zener at very low bias will oscilate.
