Test 2 is used to measure what?

• A. Insulation/resistance
• B. Continuity
• C. Inductance
• D. Capacitance

Answer: (A)

Test 2 measures insulation resistance—the ability of the insulation to resist leakage current. In practice, you apply a high DC voltage with a megohmmeter and measure the leakage current to determine resistance. A high resistance value (in the megohms range) indicates good insulation, while a low value points to moisture, damage, or aging that can cause leakage or faults. This test is used to confirm the integrity of insulation on cables, windings, and components after installation or maintenance. Continuity checks look for a complete conductive path (not insulation integrity), while inductance and capacitance measure reactive properties, not insulation resistance. So Test 2 is the insulation resistance test.
