Good evening,
I have a 35W water pump at 220 VAC, I would like to reduce its consumption, I thought of two methods:
1- use a transformer to reduce the voltage from 220V to 110V
2- use two power resistors in series of 470 ohm each and which resist a thermal dissipation of 20w each, this method will cause a voltage drop of 150V (the goal is to make the voltage drop as much as possible), so it will remain 70V for the pump.
Can the pump work if I use one of these two methods or not?
Thanks for your help.
