A generating station is producing 4.00X10^6W of power that is sent to a city located 45.0km away. The engineers must decide on the most efficient way to send this power along the transmission lines, which have a resistance of 0.500Ω. One option is to send the power at 2.40X10^3V and save the cost of building a transformer at each end of the lines. A second option is to step up the voltage using a 100:1 step-up transformer, send the power, and then step down the voltage to 2400V.
a)Determine the power lost in the transmission lines if the second option is used.
b)Should the engineers use the first or second option to transmit the energy? Explain.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
