Junior Engineer Electronics Interview Questions and Answers

Semiconductor is a material that has electrical conductivity between a conductor and an insulator.

• Semiconductors are used in electronic devices like transistors, diodes, and integrated circuits.

• Common types of semiconductors include silicon, germanium, and gallium arsenide.

• Semiconductors can be classified as intrinsic (pure) or extrinsic (doped with impurities).

PLC, Star, Delta, MCB, RCCB, SCADA, Relay, SMPS, HO, Amps are all related to electronics and electrical engineering.

• PLC stands for Programmable Logic Controller and is used for automation in industries.

• Star and Delta are two types of motor starters used in electrical engineering.

• MCB stands for Miniature Circuit Breaker and is used for protection against overcurrent.

• RCCB stands for Residual Current Circuit Breaker and is used for protection against earth leakage current.

• SCADA ...read more

Semiconductors are materials that have properties between conductors and insulators, allowing them to selectively conduct electricity.

• Semiconductors have a conductivity between that of conductors and insulators

• They can be classified as intrinsic or extrinsic semiconductors

• Common examples include silicon and germanium

Different data types in C include int, float, char, double, and void.

• int - used for integer values (e.g. int num = 10;)

• float - used for floating-point values (e.g. float num = 3.14;)

• char - used for single characters (e.g. char letter = 'A';)

• double - used for double-precision floating-point values (e.g. double num = 3.14159;)

• void - used to specify that a function does not return a value (e.g. void functionName();)
