Taneja Aerospace and Aviation Ground Service Assistant Interview Questions and Answers

Q1. What is power of transformer
Ans. 
The power of a transformer refers to its ability to transfer electrical energy from one circuit to another.
• Power of a transformer is determined by the product of voltage and current in the primary and secondary coils.

• It is important for efficient energy transfer and voltage regulation.

• Transformers can step up or step down voltage depending on the turns ratio.

• Example: A transformer with a turns ratio of 1:2 will step up

Q2. What is the unit for frequency
Ans. 
The unit for frequency is Hertz (Hz).
• The unit for frequency is measured in Hertz (Hz)

• Frequency is the number of occurrences of a repeating event per unit of time

• For example, if a wave completes 10 cycles in 1 second, its frequency is 10 Hz

Q2. Explain Compilation stages
Ans. 
Compilation stages involve preprocessing, compilation, assembly, linking, and loading.
• Preprocessing: Includes expanding macros, handling conditional compilation, and file inclusion.

• Compilation: Translates source code into assembly code or machine code.

• Assembly: Converts assembly code into object code.

• Linking: Combines multiple object files and libraries into a single executable.

• Loading: Loads the executable into memory

Q3. Logics on bit wise operators
Ans. 
Bitwise operators are used to perform operations at the bit level on binary numbers.
• Bitwise AND (&) - sets a bit to 1 only if both input bits are 1

• Bitwise OR (|) - sets a bit to 1 if either input bit is 1

• Bitwise XOR (^) - sets a bit to 1 if the input bits are different

• Bitwise NOT (~) - inverts all the bits

• Left shift (<<) - shifts the bits to the left by a specified number of positions

• Right shift (>>) - shifts the bits

Q4. Understanding of pointers
Ans. 
Pointers are variables that store memory addresses of other variables in programming languages like C and C++.
• Pointers are used to store memory addresses of variables.

• They allow direct manipulation of memory locations.

• Pointers can be used to pass variables by reference.

• Example: int *ptr; ptr = # *ptr = 10; // num now equals 10
