The teachers of geeta's school took the students on a study trip to a power generation station, located nearly 200km away from the city. The teacher explained that electrical energy is transmitted over such a long distance to their city, in the form of alternating current raised to a high voltage. At the receiving end i'm the city, the voltage is reduced to operate the devices. As a result, the power loss is reduced. Geeta listened to the teacher and asked questions about how the ac is converted to a higher or lower voltage.
