When a transmission line is energized, the wave that propagates on it is____________?
Correct answer: C. Both (A) and (B)
- A. current wave only
- B. voltage wave only
- C. Both (A) and (B)
- D. power factor wave only
Explanation
Energizing a transmission line creates a traveling electromagnetic wave, consisting of related voltage and current waves that propagate along the line. It is therefore not a current-only or voltage-only phenomenon.
