Answer:
three-phase
Explanation:
2-phase, 3-phase, and 6-phase systems are in use. The most common of these is 3-phase.
A modern industrial plant most likely uses a 3-phase system.

Additional comment
Serious research began on 6-phase power transmission systems in 1973. They have been shown to increase power transfer, and to reduce corona, magnetic fields, and audio noise compared to 3-phase systems. However, they are not in widespread industrial use.
Explain why power is generated at very high voltages.
Answer:
It's because to increase efficiency.
Explanation:
As electricity is transmitted over long distances, there are inherent energy losses along the way.

Which prosses uses a die and press to form parts
Answer:
stamping
Explanation:
Technician A says that primary vibration is created by slight differences in the inertia of the pistons between top dead center and bottom dead center. Technician B says that secondary vibration is a strong low-frequency vibration caused by the movement of the piston traveling up and down the cylinder. Who is correct? O A. Neither Technician A nor B OB. Technician B O C. Both Technicians A and B D. Technician A
Neither technician Technician or B is correct in the statement above.
What leads to primary vibration?Vibration is a factor that is said to be caused by one or more other factors that occur together at any given time.
This can be due to actors such as imbalance, misalignment, wear and looseness and others. An imbalance occurs due to a "heavy spot" that is found inside a rotating component and it will lead to vibration when the unbalanced weight is said to rotates in circles round the machine's axis.

When is the output of an OR-gate LOW?
Answer:
The OR gate is a digital logic gate that implements logical disjunction (∨) from mathematical logic – it behaves according to the truth table above. A HIGH output (1) results if one or both the inputs to the gate are HIGH (1). If neither input is high, a LOW output (0) results.
