10A transformer works on the principle of mutual induction.
The primary and secondary coils of a transformer are physically connected.
Direct current can be used to change voltage using a transformer.
The primary coil is the coil into which AC is fed.
Laminating the core prevents excessive heating.
The number of turns in the secondary coil is always equal to the primary coil.
The magnetic field in a transformer is created by alternating current in the primary coil.
E, U, and I shaped sheets are used to construct the core of a transformer.
Insulating the lamina of the core is unnecessary in a transformer.
Voltage in a transformer can be changed by varying the number of turns in the coils.
