TMEIC Electrical Design Engineer Interview Questions and Answers

Safety relay is an electromechanical device that monitors the safety functions of a machine and stops it if a safety issue is detected.

• Safety relays are used to monitor safety functions such as emergency stops, guard doors, light curtains, etc.

• They work by using input signals from safety devices to determine if the machine is in a safe state.

• If a safety issue is detected, the safety relay will open its contacts and sto...read more

Ohm's Law is a fundamental principle in electrical engineering that relates the current flowing through a conductor to the voltage across it and the resistance of the conductor.

• Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) across it and inversely proportional to the resistance (R) of the conductor.

• The formula for Ohm's Law is: V = I * R, where V is the vol...read more

The current unit is the ampere (A), which measures the flow of electric charge.

• The ampere is named after the French physicist André-Marie Ampère.

• Current is the rate at which electric charge flows through a conductor.

• Other common units for current include milliamperes (mA) and microamperes (μA).

The voltage unit is measured in volts (V).

• The voltage unit is denoted by the symbol V.

• Voltage is the potential difference between two points in an electrical circuit.

• Common examples of voltage units include millivolts (mV), kilovolts (kV), and megavolts (MV).

The current unit refers to the standard unit of measurement being used in a particular context.

• The current unit can vary depending on the field or industry, such as inches in construction or Celsius in weather forecasting.

• It is important to clarify the current unit to ensure accurate communication and data analysis.

• Examples of current units include meters for length, kilograms for weight, and seconds for time.

The resistance unit is the ohm (Ω), which measures the opposition to the flow of electric current.

• The resistance unit is measured in ohms (Ω)

• It represents the opposition to the flow of electric current

• Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current

Geometric Dimensioning and Tolerancing (GD&T) symbols are used to define the geometry of parts and assemblies in engineering drawings.

• GD&T symbols include position, concentricity, symmetry, perpendicularity, parallelism, flatness, circularity, cylindricity, profile of a line, profile of a surface, etc.

• Each symbol has a specific meaning and is used to communicate the required tolerances for manufacturing and inspection ...read more

Solid design involves creating 3D models with volume, while sheetmetal design focuses on creating 2D models that can be bent or formed into 3D shapes.

• Solid design is used for creating objects with volume and complex shapes.

• Sheetmetal design is used for creating objects that can be easily bent or formed, typically used in manufacturing processes like metal fabrication.

• Solid design often involves features like fillets, c...read more
