The tip conductor is normally connected to which voltage?

• A. Ground voltage
• B. Positive DC signal voltage
• C. Negative DC signal voltage
• D. AC voltage

Answer: (B)

Polarity in a simple two-conductor test setup: the tip conductor is the positive-side lead. In most test gear and cabling conventions, the tip is connected to the positive DC signal while the return path (the other conductor) carries the negative or reference potential, often tied to ground. This aligns with how probes and power supplies are labeled—red tip or positive lead indicates positive DC voltage. So the tip is normally connected to positive DC voltage. Ground voltage would imply the tip is at reference/zero, which isn’t the standard signal connection for the tip in this context. Negative DC voltage would typically be on the return path, not on the tip. AC voltage can appear on signal leads, but for a DC polarity convention, the tip is positive.
