Oil switches are employed for_____________?
Correct answer: C. high voltages and large currents circuits
- A. low currents circuits
- B. low voltages circuits
- C. high voltages and large currents circuits
- D. all circuits
Explanation
Oil switches use insulating oil to provide arc extinction, making them suitable for switching high voltages and large currents. Low-voltage circuits generally do not need this type of arc-quenching arrangement.
