### Step-by-Step Solution: 1. **Identify the Device**: The device used to obtain 220 V a.c. from 11 V a.c. is called a **step-up transformer**. 2. **Understanding the Working Principle**: A step-up transformer works on the principle of electromagnetic induction. It consists of two coils of wire, known as the primary coil and the secondary coil, wound around a magnetic core. The primary coil is connected to the input voltage (11 V a.c.), and the secondary coil provides the output voltage (220 V a.c.). ...

The teachers of Geeta's school took the students on a study tirp to a power generating station, loactad nearly 200km away form 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 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.
