1.	A device is used to transform 12V a.c. to 200V a.c. (1) What is the name of this device? (2) Name the principle on which it works.
Answer» 1. Since the device is being used to step up 12V a.c. to 200V a.c., it is called a step up transformer. 2. A transformer works on the principle of mutual induction. 3. “When an alternating current is passed in the primary coil wound on the soft iron core, an induced emf- is produced in the secondary coil, wound on a soft iron
