Hello.
I need to measure selenoid current. (The selenoid controls presure reducing valve) It is powered by PWM. I don't know where to measure the current. In series with switching transistor or in series with selenoid and reverse diode? The measured current should be equivalent to DC current.
Thanks for help.
