What is the intuition as for why we subtract the two values in the second scenario? I know how to do the calculations, but I struggle a bit to intuitively understand why the voltmeter will not show 40 V in the second case as well. It is easier to talk about this ...
Since voltmeters are always connected in parallel with the component or components under test, any current through the voltmeter will contribute to the overall current in the tested circuit, potentially affecting the voltage being measured. A perfect voltmeter has infinite resistance so that it draws ...

The arrowhead in each diode symbol points in the permitted direction of current flow. Arranged in a bridge, four diodes will serve to steer AC through the meter movement in a constant direction throughout all portions of the AC cycle:
voltmeter is represented by the symbol V.) Ammeters are connected in series with whatever device’s current is to be measured. A series connection is used because objects in series have the same current passing through them. (See Figure 3, where the ammeter is represented by the symbol A....
The symbol for continuity looks like an arrow pointing right into a plus sign (see above). You may also see a “speaker” symbol or something that indicates you will hear a tone or beep. Use continuity to troubleshoot potential breaks in a line. Attach each of the multimeter leads to ...
