why the input power factor varies with different loads while the output power factor stays constant?

input power factor for short circuit.
output power factor for open circuit stays constant with different loads

Due to variation of loads at different times the power factor changes .
wHEN THE LOAD IS MINIMAL OUT PUT CHANGES ARE MINIMAL.

Well the voltage level might stay the same on the output side but the wattage will change depending on the load
