The principle of a transformer is based on electromagnetic induction.

• Transformers work on the principle of transferring electrical energy between two or more coils through electromagnetic induction.

• They consist of two coils, known as the primary and secondary coils, which are wound around a common magnetic core.

• When an alternating current (AC) flows through the primary coil, it creates a changing magnetic field around the core.

• This changing magnetic field induces a voltage in...read more

Storage classes in C define the scope and lifetime of variables.

• There are 4 storage classes in C: auto, register, static, and extern.

• Auto variables are stored in memory and have local scope.

• Register variables are stored in CPU registers for faster access.

• Static variables retain their value between function calls.

• Extern variables are declared outside of any function and can be accessed by other files.
