I'm studying Zener example and it doesn't make sense to me:
in the above picture i can see that input is 26.4V and Zener voltage 14.56V. when load 1k connected.
but in the above picture i can see that input is 21.6V and the Zener voltage is actually bigger? 14.561V.
what is not making sense to me: how he wants to add load when he operate the Zener at knee point. and he uses the estimated linear model of Zo or dynamic resistance.
Q1: is this example wrong and because he is using estimate model of zener on knee of the zener?
Q2: i mean OK, you can calculate Rmax but then the slope will change and you cant assume Rz is 14 ohm right??? and this Vo in second case is larger than first case is wrong right??
Note: this example is taken from university material. and I'm not studying there but assuming the tutor is mistaken by providing this example? unless he want to tell students that this example is actually not right at the end???! or all my assumptions are wrong?
