Electric transmission is accomplished at very high voltages when long distances are being covered. This reduces the currents involved and makes the transmission line far more efficient. On the other hand, we don't want extremely high voltages in our houses! Describe how utility companies can lower the voltages to reasonable levels and still keep their systems efficient. A 100 MW power station generates energy at 26.0 W. The power lines must carry only 200 A of current to be efficient enough. To what voltage must the potential be increased? Show your work (formula, substitution, answer rounded correctly and with the appropriate unit). lI A group of students found an old DC electric motor in a box. They were looking for a small generator they could use to power their computer while they were out camping. Explain how they might do this with the motor they found. A cell phone battery has 9.00>
