Which of the following statements is incorrect for alternating current...
This statement 'It has a constant value.' is incorrect for alternating current.
- Alternating current does not have a constant value. Its value always changing means alternating current reverse its direction periodically.
- Alternating current (AC) can be transferred over long distances.
- It is also cheap to generate AC as compared to direct current (DC).
- Voltage can be changed easily in alternation current because the high voltage is reduced to low voltage when it is transferred from the power station to houses.
- The loss of power during transmission in alternating current is also less as compared to direct current.
- The conversion of Alternating current to direct current is easy.

Which of the following statements is incorrect for alternating current...
Understanding Alternating Current (AC)
Alternating current (AC) is an essential concept in electrical engineering and power distribution. Among the statements provided, the claim that "it has a constant value" is incorrect. Here’s why:
Nature of Alternating Current
- AC is characterized by its periodic change in magnitude and direction.
- Unlike direct current (DC), which flows steadily in one direction, AC oscillates, creating a waveform that is typically sinusoidal.
Key Properties of AC
- Transmission over Long Distances: AC can be transmitted efficiently over long distances due to its ability to be transformed to higher voltages, reducing energy losses during transport.
- Cost-Effectiveness: The production of AC is generally cheaper than that of DC, especially for large power generation systems, making it a preferred choice for electrical grids.
- Voltage Transformation: AC voltage can be easily adjusted using transformers, allowing for efficient distribution and use in various applications.
Conclusion
In summary, while AC has many advantages, including efficient transmission and cost-effectiveness, it does not have a constant value. Instead, it fluctuates continuously, which is a fundamental aspect of its behavior. This distinction is crucial for understanding how AC systems operate in real-world applications.
