Answer 1

The correct answer is:

(b) Output impedance

Output impedance refers to the impedance presented by the measuring device across its output terminals to the associated external circuitry. This parameter is important as it influences how the device interacts with connected load circuits, affecting signal transfer and accuracy. High output impedance can cause voltage drops and reduce the efficiency of signal transmission.
