This is basically an off-shoot from http://arduino.stackexchange.com/questions/20569/unexpected-output-pin-behavior-was-relay-on-off-doesnt-loop. It's the same schematics and so on, however, I'm now wondering what the output voltage and current is.

I've a 9V battery and the MOSFET transistor from the arduino starterpack (doesn't say the specs) connected to the 5V pin on the board. I need the following output current/voltage for it to activate a solenoid:

• 6V: 160 mA
• 7V: 190 mA
• 8V: 220 mA
• 9V 240 mA
• 10V :270 mA
• 11V :300 mA
• 12V :320 mA

and I'm just not sure how to calculate it since I'm not sure about the output from the transistor and all the way to the solenoid.

The solenoid: http://www.electrokit.com/en/plastic-water-solenoid-valve-1-2-12v.51108

It should be solenoid instead of relay in the schematics
