Hi all,
I'm looking into zener diodes and i have 2 questions . I found an article on simple zener diode circuits and there is something i don't understand (screenshot article in attachment).
1) The article states that the zener is in series with the Resistance R ? In series for me means ( + pole of a device connect with  pole of another one). But since the resistor R has no polarity how can we say it's in series then.
2) Will the zener diode block current flow ? > so no current flow in the whole circuit until the reaches his breakdown voltage.
I'm confused if it's simultaniously or in two steps ( circuit in article). Does the Zener takes all the voltage and current (because it blocks current flow) until it reaches his breakdown voltage AND THEN current flow in the whole circuit. Or does the load follow the voltage of the zener diode ? > Zener = 1V  Load = 1 V , Zener = 2v  Load = 2 V , etc ...
Thx Mike
