Question

An anchor line for a tower needs to be replaced the tower is 48ft tall The anchor line 73 ft long how far from the tower can it be placed to the nearest foot​

Answer 1

Answer:

ANSWER

As we know that Power=${I}^{2}_{rms}$

So to decrease power loss ${I}_{rms}$and R must be lower for a constant power supply.

To decrease I

rms

,V

rms

must be increased by step up transformer to get same power in step up transformer

Output power = Input power

$V </p><p>S</p><p> </p><p> I </p><p>S</p><p> </p><p> =V </p><p>P</p><p> </p><p> I </p><p>P</p><p> </p><p> </p><p>∵V </p><p>S</p><p> </p><p> >V </p><p>P</p><p> </p><p> so I </p><p>P </p><p>3+</p><p> </p><p> </p><p> I </p><p>S$ so loss of power during transmission become lower. We can again reduce voltage by using step down transformer.
