  1. Question 1

    Q1. A three-phase AC system is used in a industrial setting to power heavy machinery. What is the primary advantage of using a three-phase system?

    • A) It increases the power factor of the system
    • B) It reduces the current drawn from the mains due to the phase difference
    • C) It reduces the voltage drop in the transmission lines
    • D) It allows for more efficient use of copper wire in the transmission lines

    Answer: It reduces the voltage drop in the transmission lines

    Explanation: The three-phase system reduces the voltage drop in the transmission lines due to the reduced current flow, making it more efficient.
