Utility company power lines carry what type of current?

Alternating
Direct
Pulsating
Static

The correct answer is: Alternating

Utility company power lines carry alternating current because it is more practical and efficient for long distance transmission. Alternating current (AC) allows for the use of transformers which can change the voltage for the transmission and distribution of electrical energy. Direct current would require a much higher voltage, resulting in significant energy losses. Pulsating and static currents are not commonly used for power transmission because they are not able to deliver energy as effectively as alternating current.
