A factory requires a power of 90 kW. The energy is tranmitted to the factory through a `2.5Omega` line wire .If 10 % of the power generated is lost in transmission , calculate
The trasmission line current
the potential difference at the power genrating station
the potential drop due to line resistance .

Here , `("power of the generating station")/("power required for the factory ")=(100)/((100-10))`
`=(100)/(90)`
or , power of the generating station`=90xx(100)/(90)=100W`
According to the equation , P =VI ,
potential difference at the generating station ,
`I=(P)/(I)=(10000)/(63.25)=1581V` (approx)
