What are the advantages and disadvantages of instrumentation amplifier?
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.
What are transmission cables made of?
Transmission cables are made of conductors and insulating material covering that conductor.

What are Overhead power cables advantages and disadvantages?
Advantages=The main advantage is that they are easier to repair if damaged (Usually just go up a ladder and do the necessary work)They are not restricted by the landscape that they are in e.g. you can easily suspend them over a motorway or riverAlso they have a less chance of electrocuting people as they are so high upLose less energy then if they were underground as they do not have any good conductors near them to transfer energy away as easilyCheaper to set up and maintain than if theyw ere underground Disadvantages=Main problem is that they visually pollute the areas they are set up inSuffer from problems like vandalism, assisting terrorism (Easy access), and lightning strikesBirds and low flying aircrafts can sometimes fly into them
