Samsung E&A Electrical Design Engineer Interview Questions and Answers

Discussion on soil mechanics starting from modulus of elasticity to liquifaction

• Modulus of elasticity is a measure of soil stiffness

• Soil strength is important in determining its ability to withstand loads

• Liquifaction occurs when soil loses strength and behaves like a liquid

• Factors affecting soil strength include soil type, moisture content, and stress history

• Liquifaction can lead to soil failure and damage to structure

The question covers power factor of transformer, types of DC machine, working principle of AC alternator, and DC motors.

• Power factor of a transformer is the ratio of real power to apparent power.

• Types of DC machines include DC motors and DC generators.

• AC alternators work on the principle of electromagnetic induction to convert mechanical energy into electrical energy.

• DC motors convert electrical energy into mechanical ...read more

A multimeter is an electronic device used to measure voltage, current, and resistance in electrical circuits.

• It can measure AC and DC voltage

• It can measure AC and DC current

• It can measure resistance

• It can also measure other electrical parameters such as capacitance and frequency

• It typically has a digital display for easy reading

• Examples of multimeter brands include Fluke, Klein Tools, and Extech

Flow transmitter senses flow and transmits signal to controller in selected range.

• Use a flow transmitter that is capable of sensing flow and transmitting a signal.

• Connect the flow transmitter to the controller using appropriate wiring and communication protocols.

• Configure the flow transmitter to operate within the desired range.

• Ensure proper calibration of the flow transmitter to accurately measure and transmit flow da...read more
