Final answer:
The simultaneous use of AC packs and LP ground cart is not possible. Nonzero DC current cannot be produced by adding together AC currents.
Step-by-step explanation:
The statement is FALSE.
The limitation of simultaneous use of AC packs and LP ground cart means that AC packs and LP ground cart cannot be used at the same time.
Ohm's law relates the current flowing through a conductor to the voltage applied and the resistance of the conductor. It states that the current is directly proportional to the voltage and inversely proportional to the resistance.
Nonzero DC current can be produced by adding together direct currents, not alternating currents. Alternating currents flow in different directions over time, so when they are added together, the resulting current will fluctuate and not remain constant.
