From part b we have found the current in one of the transmission lines to be 2.5 A using the equation P = IV. From part c we have found the power loss to be 18.75W using the equation P = I^2 R. From part d we have found the voltage drop to be 7.5 V using the equation V = IR. The voltage drop here is referring to the voltage at thje receiving end of the transmission lines, a pair of transmission lines will have a voltage drop of 7.5 * 2 = 15 V, the answer would then be 22000 - 15 = 21985 V.

HI@@@ URGENT.
WHEN DO WE USE SINR / SINI?

from MEDIUM TO AIR?
