Answer:
B) alternating current
Step-by-step explanation:
Alternating currents are different from direct current. These form of currents are used to transport power from generating stations over large distances.
- Alternating current is a current that reverses direction periodically.
- The voltage also reverses and leads to little loss in voltage.
- This current reversal makes them desirable for long distance transmission coupled with the little loss in voltage.
- Transformers used to change the voltage of these wave forms.
- The lesser loss in voltage makes AC desirable for long distance transmission.
