The main advantages are that they don't spoil the appearance of the countryside and can't damage flying birds, and that they are protected from the weather. The main disadvantage is the much larger cost of installing them.
Overhead transmission lines are less expensive, in most cases, significantly less expensive, than underground cables. Underground transmission cables require insulation, cooling systems, and -the most expensive feature- excavation!
power cables under ground rather then overhead.
A. you can go under water. D. if they break you die.
Advantage: everything. Disadvantage: cables and less mobility.
Murry for long underground cables test but varley usually for short distance.
Advantages:Even a small value of input voltage can be amplified using instrumentation amplifier.Disadvantages:For transmission purpose for long range, noise also gets superimposed along the original wave. Therefore specific cables are used to reduce noise.
Transmission cables are made of conductors and insulating material covering that conductor.
Twisted-pair cables Coaxial cables
yes and it good for this jop
because its to expensive.
