For the circuits shown in Fig. 6, voltage meters and ampere meters are used to measure
the voltage across the load and their current flow. If the Red Probe is plugged into the “+”
terminal of the voltage meter and ampere meter, which circuit(s) show both the correct
connections and measurement values? State all correct answers.
The Attempt at a Solution
I have figured out that circuit D is correct.
Circuit F is wrong due to incorrect method of connecting the voltmeter and ammeter.
Circuit A and E has wrong polarities in one of their values.
Now Circuits B and D are tricky for me. Circuit B's voltmeter has a reading which is only 0.1 V lower than the EMF. Is this still considered correct?
As for Circuit D, The value of current I got through calculation was -0.91 A. Ammeter, however, shows a reading of -1 A. I am confused on whether or not this -1 A value is a rounded off answer. Can somebody please guide me on these 2 circuits.
