When electricity is transported long distances via large overhead transmission lines the voltage can be transformed up to volts. A. 250000 B. 500000 C. 10000 D. 100000?
When electricity is transported long distances via large overhead transmission lines, the voltage can be transformed up to 500,000 volts (B). This high voltage reduces energy loss during transmission, allowing for efficient delivery of electricity over long distances.
Why over head lines are used in Extra high voltage AC lines?
Overhead lines are used in extra high voltage (EHV) AC transmission primarily due to their cost-effectiveness and ease of installation compared to underground cables. They allow for efficient transmission of electricity over long distances with minimal energy losses, as the air acts as an insulator and facilitates heat dissipation. Additionally, maintenance and fault detection are more straightforward with overhead lines. Overall, these factors make overhead lines a preferred choice for EHV AC systems.
In Pulse Code Modulation if the transmission path is very long?
In Pulse Code Modulation (PCM), if the transmission path is very long, the signal may be subject to degradation due to factors such as attenuation, noise, and interference. To mitigate these effects, repeaters can be used to amplify the signal at intervals along the path. Additionally, error detection and correction techniques can be implemented to ensure data integrity. Ultimately, careful consideration of the transmission medium and encoding techniques is crucial for maintaining signal quality over long distances.
Why resistor used in transmission lines?
Resistors are used in transmission lines primarily for impedance matching and to minimize signal reflections. By dissipating excess energy, they help maintain signal integrity over long distances. Additionally, resistors can be employed in termination circuits to prevent standing waves, which can lead to interference and degradation of the signal. Overall, their use enhances the efficiency and reliability of signal transmission.
What are advantageand disadvantage of analog transmission and analog transmission?
Analog transmission offers advantages such as simplicity and ease of implementation, making it suitable for basic communication systems. It typically requires less bandwidth than digital transmission, allowing for efficient use of available frequencies. However, its disadvantages include susceptibility to noise and distortion, which can degrade signal quality over long distances. Additionally, analog systems lack the error correction capabilities and data compression efficiencies inherent in digital transmission, limiting their overall performance and reliability.
Why is serial communication preferred over parallel communication for long distance wan links?
Serial communication is preferred over parallel communication for long-distance WAN links primarily due to reduced crosstalk and electromagnetic interference. In parallel communication, multiple wires transmit data simultaneously, increasing the risk of signal degradation over long distances. Serial communication, using a single wire or pair, minimizes these issues and simplifies the design and implementation, allowing for higher data rates and longer transmission distances without significant loss of integrity. Additionally, serial connections require fewer physical resources, making them more cost-effective for WAN applications.

What is serial transmission?
Serial transmission is a method of transmitting data where one bit is transmitted after another in a single wire. Serial transmission is usually used to transmit data between two computers as it is less expensive, yet at a cost of a slightly slow speed. A minimum of two wires is needed for serial transmission, which is less compared to a minimum of eight wires in parallel transmission. Serial transmission is used to send data over long distances as the bits are less likely to get out of order. It is used in devices such as modems, bar code readers and light pens .

How do high voltage transmission lines use electricity to efficiently transport power over long distances?
High voltage transmission lines use electricity to efficiently transport power over long distances by increasing the voltage of the electricity. This allows for the power to travel long distances with minimal loss of energy. The high voltage reduces the amount of current needed, which in turn reduces the energy lost as heat during transmission.

What happens when electricity is transmitted over long distances?
When electricity is transmitted over long distances, it can experience energy losses in the form of heat due to resistance in the transmission lines. This can lead to a decrease in voltage levels, which may require additional equipment such as transformers to boost the voltage back up along the way. Additionally, environmental factors like temperature and weather conditions can also affect the efficiency of electricity transmission over long distances.
