Micron Electricals Electrical Site Engineer Interview Questions, Process, and Tips

A circuit is a closed loop through which an electric current can flow.

• A circuit consists of a power source, conductors, load, and a switch.

• Electric current flows from the power source through the conductors to the load.

• Examples of circuits include simple ones like a flashlight circuit or complex ones like a computer motherboard.

AC motors use alternating current while DC motors use direct current. AC motors are more commonly used due to their simplicity and efficiency.

• AC motors use alternating current, while DC motors use direct current

• AC motors are more commonly used in household appliances and industrial applications

• DC motors are often used in small applications like toys and tools

• AC motors are simpler in construction and more efficient than

Distribution boards are used to distribute electrical power to various circuits and equipment.

• Main distribution board (MDB) is used to distribute power to sub-distribution boards.

• Sub-distribution boards (SDB) are used to distribute power to final circuits.

• Final distribution boards (FDB) are used to distribute power to equipment.

• Motor control centers (MCC) are used to control and distribute power to motors.

• Lighting dist...read more
