Well that’s a bummer. I was hoping for an Ohm or so, at least. The whole purpose was to calculate the resistance and wattage you need for the resistor. Of course, the goal is to match the resistor’s resistance to the solenoid’s resistance. Some quick numbers crunching comes up with using a one Ohm resistor plus a one Ohm solenoid will draw about 6 Amps. So. a resistor dropping 6 Volts, with 6 Amps current would mean 36 Watts. Meaning a One Ohm, 36 W resistor is called for, or maybe 50 W for availability. IF it truly is one Ohm resistor & solenoid. But I suspect you already know this.
