The teachers of Geeta's school took the students on a study trip to a power generating 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 (ac) raised to a high voltage. At the receiving end in 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.
Write two values each shown by the teachers and geeta,

Geeta listened to the teacher and asked questions about how the ac is converted to a higher or lower voltage. Explain with an example , how power loss is reduced if the energy is transmitted over long distances as an alternating current rather than a direct current .

At the receiving end is 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 question about how the ac is converted to a higher or lower voltage. (a) Name th device used to change the alternating to a higher or lower value. State one cause for power dissipation in this device. (b) Explain with an example, how power loss is reduced if the energy is transmitted over long distance as an alternating current rather than a direct current, (c) Write two values each shown by the teachers and Geeta.
