Meters and troubleshootingQuestion 734 of 1506

Which action reduces the error caused by cable resistance in a voltage signal system?

  1. Use a lower-resistance indicator
  2. Use heavier wire
  3. Use longer conductors
  4. Use thinner conductors
Show answer

Correct answer: Use heavier wire

Lower cable resistance means less voltage drop. A high-resistance indicator also helps.
