My guess is that you are asking why a 1.8A rated freezer only draws 0.8A.
Power and current ratings are the worst case and rarely reflect the actual drain because the purpose of such information is to be sure you have enough.
You reduce the current in a circuit by increasing total resistance or impedance.
It is not clear what you are asking, "drop electric amps"?
you can adjust desirable magnitude of current by adjusting the value of resistance through rheostat
how do we drop electric amps. full load but show drop.
