In a properly designed and terminated transmission line, the electrical length is infinity. Any discontinuity in the line, such as an open, short, or change in impedance, results in a reflection of the travelling wave in the line. That reflection distorts the original signal and, if big enough, can damage things, like the transmitter.

What sagging electrical transmission lines show that solids contract as they cool?
Sagging electrical transmission lines demonstrate that solids contract as they cool because the material of the lines, typically made of metals, undergoes thermal contraction when temperatures drop. As the metal cools, it shrinks, leading to a decrease in tension in the lines, which causes them to sag under their own weight. This behavior is a direct consequence of the physical properties of solids, where the atomic structure tightens as thermal energy decreases, resulting in reduced length and increased sagging.
What is length of the towers that is used on transmission lines?
That is depends on the factor of sag and clearance required. And also on the level of voltage transmission used.
Is ohm's law applicable to high transmission lines?
Ohm's law is applicable to all electrical circuits.
What is meant by return conductor in transmission lines?
The return conductor in transmission lines refers to a path that completes the electrical circuit by allowing the return of current to the source after it has traveled through the load. In many transmission systems, this can be a physical wire or a designated path in the ground or environment. The return conductor ensures that the electrical current can flow continuously, helping to maintain the efficiency and stability of the transmission system. It is critical for minimizing losses and maintaining signal integrity.
What is the basic parameters of transmission lines?
the basic parameters of transmission lines are R,L,C and G...........
Why are transmission lines less than 80km considered short?
The transmission lines which have length less than 80 km are generally referred as short transmission lines. For short length, the shunt capacitance of this type of line is neglected and other parameters like electrical resistance and inductor of these short lines are lumped.
What are electrical transmission towers for?
Electrical transmission towers are meant to hold the power lines and to carry electricity.
Why you use distrubuted facts about transmission lines?
This makes no sense. You need to define what you mean by "distributed facts".
Why are electrical transmission towers so close to the street?
To support the power lines. A power line is connected from the electrical transmission tower to the transformer to help bring electricity to the generator.

Single most common metal in electrical transmission lines?
ACSR - Aluminum Cable Steel Reinforced
Is ohm's law applicable to high transmission lines?
Ohm's law is applicable to all electrical circuits.
What does power loss in electrical transmission mean?
The term, 'power loss', describes the rate of energy losses caused by the load current in the transmission lines
Why transmission lines are thicker than TV cable wires?
Transmission lines are thicker than TV cable wires because the transmission lines are used to transmit both low freq and high freq signals. And the losses of the transmission lines depend the resistance of the line which inturn depend upon length and area. As we have to transmitt the signals over long distances the transmission lines are thicker in size.Whereas in TV cable wires the construction is totally different in which transmission of signals is in between two conductors thereby avoiding losses.Therefore there is no necessity for these lines to be made thicker. That is why transmission lines are thicker than TV cable wires.
What are power lines used for?
Answer youtubeAnswerThere are two categories of 'power lines': 'transmission lines' and 'distribution lines'. Transmission lines comprise lines supported by transmission towers ('pylons') and distribution lines comprise lines supported by poles. In both cases, their function is to transport electrical energy from the generating stations to the consumer. Transmission lines are normally part of the grid system, a network which links many generating stations and load centres (usually located near large towns, for example); distribution lines link these load centres to consumers -factories, commercial buildings, residences.
Define parallel line?
Lines are parallel if they lie in the same plane, and are the same distance apart over their entire length. Parallel lines remain the same distance apart over their entire length. No matter how far you extend them, they will never meet.
