Question: impedance) adds in series just as resistance adds in series and inductive reactance/impedance adds in series. Remember: ohms always add in series, no matter what their source(s); only farads add in parallel (omitting siemens or mhos, the units for conductance and admittance and susceptance, which of course also add in parallel).

To measure DC voltage, you put the meter in parallel with the load and add a resistor in series with the meter to limit the flow of current. So, if you put a 1000 ohm resistor in series with the 0.001 amp meter and put 1.0 volts across the two, you would have 1.0/1000 or 0.001 amps flowing through the meter.
