It is not right to say that it is always dangerous to use
long cables, or that shortest possible cables are always constitute the best alternative
in electrical circuits. However, shorter cables do present some advantages. Some of
these have been identified in the answer above. I would like to add the following to the
ones identified.
- Longer the cable, greater the
chances of their getting damaged. This may result in leaking of current due to poor
insulation. For high voltage circuits this can be
dangerous. - Longer cables cost
more.
However, in some cases it may be
desirable to increase the length of cable to organize the neat cable layout that avoids
excessive crisscrossing of cables, and cables running across some of the other
components of the circuits. In permanent electrical circuits running over long
distances, provision is usually made for some additional length of cable so that any
subsequent repairing of faults in the cable will not result in the available length of
cable falling short of the minimum required to cover the distance between the two ends
of the cable.
