🔍 Key Concepts

• How a capacitor behaves in a DC circuit (initially like a short circuit, then like an open circuit as it charges) • What a hand‑cranked megohmmeter actually measures (insulation resistance over time, not just an instant value) • The difference between behavior of a good capacitor vs a shorted or open capacitor on an insulation test

💭 Think About

• When you first apply a DC test voltage across a discharged capacitor, what does the current do at the instant of connection, and what does it do a few seconds later? Translate that behavior into resistance readings. • For each answer choice, picture the needle motion: does that pattern match a component that starts as a short and becomes an open, or the opposite? • Ask yourself: if the needle stays at a very low resistance, what fault does that suggest? If it stays at infinity, what kind of fault does that suggest?

✅ Before You Answer

• Confirm that a healthy capacitor on a DC insulation test will show a changing resistance over time, not a fixed value. • Make sure you know that infinity on a megohmmeter represents very high insulation resistance (open circuit) and that a very low value represents a short or leakage. • Verify that the correct pattern should show the capacitor charging up during cranking, which affects current and thus the apparent resistance.
