how can we use zener diode as a voltage regulator.
In: Engineering
A zener diode only wants to negitive voltage to equal it’s zener breakdown voltage. As you decrease the voltage beyond that point, it will draw more current to bring the voltage back to the point that it wants.
Think of it like one of those large circular drains in a pond. When the water level is below the lip of the drain, no water current flows. As you increase the water level above the lip of the drain, more water flows until the pond is at the lip level. Higher water above the lip, more current to bring it back to the expected point.
