356269 A transformer works on the principle of

356270 A transformer changes the voltage

356271 Statement A :
When a current flows in the coil of a transformer then its core becomes hot.
Statement B :
The core of transformer is made of soft-iron.

356272 Quantity that remains unchanged in a transformer is

356273 Consider the statements.
I.
Most of the electrical devices we use require \(AC\) voltage.
II.
Most of the electrical energy sold by power companies is transmitted and distributed as alternating current
III.
\(AC\) voltages can be easily and efficiently converted from one voltage to the other by means of transformers.
