    I have no use of this knowledge but it's a pleasure to learn it anyway. Extremely well made and clear.

    Don't you think, the reduction in the value of resistor across zener diode can burn zener diode when load is removed..? As zener diode works with little current like 20mA & this condition will cause current surge...

      No really. In fact, if we apply Ohms law here, I = U/R = 10/2000 = 0.005. So the current will be 5 mA.
