In ON state, the voltage across load is equal to Zener voltage.

What if, the unregulated power supply will be replaced with the regulated power supply?

25v is supply voltges. Zener regulates these volts. 12v zener means it regulates 12volts. So load volt is 12v.
So we use ohms law formula I=V/R.
So we use ohms law formula I=V/R.

I think since it's an unregulated power supply, 25 V tend to fluctuate.
A Zener diode in reverse config offers no impedance above its breakdown voltage, in this case, 12V.
So a maximum of 12V can be found across that Zener diode which is parallel to RL(thus the same voltage across RL also).

Why particularly use 12v in load current?

Here zener diode is coming parallel to load.

Why only 12 volt used here.
Then What is 25v?

Why doesn't the first 100 ohm resistor add to the series resistance?
