    Oct 30, 2011 · I wonder what would happen if you put a ~39uF 250VAC capacitor in series with the grinder. 39uF @ 50hz would limit the current to 2.8A (644W) I have no idea what sort of effect it would have on the grinder motor though. If the grinder started spinning you could then bypass the cap with a switch or relay+timer when it was up to speed. hehe, note the word "bypass", not "short out" 39uf @

    From what I see, this circuit is used to limit the inrush current only. For instance, an inverter may have a very big input capacitor. When you connect the power, the current can be very high (even tens of amperes). When you put this circuit, the resistor is put in series with the load; at turn on the current is limited at 12V/3.3Ohm = roughly 4 A.
