The sparking between two electrical contacts can be reduced by inserting a___________?
Correct answer: A. capacitor in parallel with contacts
- A. capacitor in parallel with contacts
- B. capacitor in series with each contact
- C. resistance in line
- D. none of the above
Explanation
A capacitor connected across the contacts provides a path for the sudden transient current and reduces the voltage rise that produces an arc. A series capacitor would not provide the usual contact-spark suppression arrangement.
