NOTE : You need to take a critical voltage reading, but you do not have a high impedance meter available.
Instead, you connect two lower impedance meters in series and place them across the component in question.
You add the readings shown on the two meters to get your measurement.
Compared to using just one of the lower impedance meters, what is the advantage of using two meters connected in series?
A. Input impedance increases and voltage-measuring accuracy increases
B. Frequency response of the test setup doubles
C. Accuracy of current measurements decreases
D. Input impedance decreases and voltage-measuring accuracy increases
