Current Measurement with switches

Started by Lauren Bitikofer

Connect simple circuit, battery, resistors and DPDT switch in series.  Put DMM in Current mode and put leads across switch.  With the switch closed there should be no current displayed on the meter as it all goes through the switch.  If you put the SPST switch in the circuit the DMM functions as it should showing no current with the switch closed.  I can send pictures if my wording here isn't clear.  Thank you.
