D) Capacitance

Question

Quizplus · Accepted Answer

Polarity is important when measuring DC (Direct Current) because the direction of the current flow is constant and the measurements can be affected by reversing the polarity. In AC (Alternating Current), the direction of the current flow constantly changes, so polarity doesn't have a significant effect on the measurements. Resistance and capacitance also don't rely on polarity for accurate measurements.
