So when I have two zeners connected, I should get less voltage than if I had one, but this is NOT the case!!! Why? I don't understand- two zeners of say 1000 V each- say we have a power source than provides 2500 volts- then we should get only 500 V. With one of these zeners, we should get 1500 V. But it's almost reversed, and I don't get why.. Thanks!!!
