🔍 Key Concepts

• Megohmmeter (megger) is designed to measure very high resistance (insulation), not normal low resistance continuity • Think about what reading you’d expect on a good, intact motor winding when measuring insulation resistance end‑to‑end • Compare faults: open coil vs. shorted/low‑resistance path vs. just being dirty or loose

💭 Think About

• Ask yourself: if insulation is good between the ends of a motor winding, should the megohmmeter show a very high resistance or a low resistance? • Which option describes a condition where current can pass too easily between those two points, instead of being well insulated? • For each wrong choice, picture what the meter would actually do: what would an open circuit look like on the meter, and what would simple dirt or looseness usually cause?

✅ Before You Answer

• Be clear on what a megohmmeter actually measures (insulation resistance in megohms, not normal ohms). • Verify which condition would create a low‑resistance path between the ends of that individual winding. • Eliminate any answers that would more likely cause very high resistance (open circuit) rather than a low reading.
