Should it not be equivalent to load voltage? as it comes across the load?

When we need to be applied Thevenin we take the load out the circuit and consider two terminal a And B (Rth, Vth).
Rth = the total input impedance in the circuit and we can apply it in two cases.
case 1: if they do not have to depend on the source we turn off all independent source Voltage source (Short Circuit) Current source ( open circuit).
case 2: if has a depend on the source we consider Voc = 1 v between terminal a and b or io = 1 A.
Rth = Vo/io.
Vth => Voc between two terminal.
Rth = the total input impedance in the circuit and we can apply it in two cases.
