🔍 Key Concepts

• Difference between measuring voltage, resistance, and continuity • What it means for a circuit to be energized (live) versus de‑energized • Which instruments are safe and appropriate to use on a live circuit

💭 Think About

• Ask yourself: when a circuit is energized, which quantity can you safely measure across a fuse without first shutting power off? • Think about which tools are normally used with power off to avoid damage to the meter or giving a false reading. • Consider what reading you would expect across a good fuse versus a blown fuse when the circuit is live.

✅ Before You Answer

• Identify which instruments are meant for use on de‑energized circuits only (especially high‑resistance/insulation testers). • For each option, decide: does this tool normally measure voltage or resistance/continuity? • Visualize placing the meter leads across both ends of the fuse in an energized circuit and determine what the safe, meaningful measurement would be.
