i could use a current source with which i could deliver 10mA at its o/p by connecting a series resistor at its o/p. So that all the voltage drops at that series resistor and thus passing the 10mA current only to the reed contact under measurement!
Yes I got it in this way: When high voltage is passed through the contact. NO, no voltage is "passed through" a contact Erik |
