Suppose 59 kW is to be transmitted over two 0.135 2 lines. Estimate how much power is saved if the voltage is stepped up from 190 V to 1900 V and then down again, rather than simply transmitting at 190 V. Assume the transformers are each 99% efficient. Express your answer using two significant figures. 1 Psaved = Submit Request Answer ? kW Suppose 59 kW is to be transmitted over two 0.135 2 lines.
