Q6. What is the principle of transformer
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
Q7. storage class in c
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.
Q8. Write code on Merge sort
