Which statement best describes what DC mode measures on a multimeter?

• A. Alternating voltage components
• B. Noise levels
• C. Steady voltages and currents
• D. Peak-to-peak values

Answer: (C)

Direct current is unchanging, so DC mode on a multimeter is designed to read constant voltages or currents. The display reflects a stable value for sources like batteries or DC power supplies, not time-varying signals. It won’t quantify alternating components, ripple, or noise, and peak-to-peak swings require a different measurement (AC mode or another instrument). So DC mode best describes measuring steady voltages and currents.
