Question

(D) None of these
59. If a generating station wants transmit a given power (VI) = 44,000 watts to a city which is 100 miles apart,
then it can be transmitted
(A) at a voltage 400 volts and a current of 110 amperes
(B) at a voltage 11,000 volts and a current of 4 amperes
(C) both (a) and (b)
(D) None of above
duction current and thus retains the​

Answer 1

Answer:

( B )

Explanation:

as given cities are miles apart

so we have to minimise current loss ( required wire length will be long )

but we know

P = VI ( constant )

we can minimise the current loss by increasing voltage and decreasing the value of current.

that's why answer should be option (B )
