Preview Questions Electrical Engineer | Role Specific Skill

Question 1: In an automotive electrical system, how does a relay function?

Which action should you take?

Choose only one option

It acts as a backup power source in case of failure

It stores energy in a capacitor for future use

It allows a low-current signal to control a higher-current circuit

It regulates the voltage across the electrical system

Question 2: What is the best approach to troubleshoot a vehicle's HVAC system that is not blowing air despite the blower motor functioning?

Which action should you take?

Choose only one option

Check the blend door actuators and related wiring

Inspect and clean the HVAC control module

Replace the blower motor

Replace the cabin air filter

Question 3: How do you calculate the power requirements for an electric vehicle's auxiliary systems?

Which action should you take?

Choose only one option

By using a standard power consumption model for all vehicles

By focusing only on the energy needs of the motor

By reducing the number of auxiliary components

By analyzing the energy consumption of each component and the power rating of the battery

Question 4: In an adaptive cruise control system, what is the function of the radar sensor?

Which action should you take?

Choose only one option

To measure the distance to the vehicle in front and provide feedback to the ECU

To adjust engine speed to match the driver's input

To monitor tire pressure and adjust throttle

To control the vehicle's steering angle in tight turns

Question 5: What is the effect of using a dead-zone in control systems for automotive applications?

Which action should you take?

Choose only one option

It increases the overall speed of the system's response

It prevents small fluctuations from affecting the system response and reduces noise

It stabilizes the system by increasing sensitivity to small changes

It makes the system more responsive to rapid changes

Question 6: In the context of electric vehicles, what does the term "state of health" (SoH) of a battery refer to?

Which action should you take?

Choose only one option

The voltage level of the battery

The current charge level of the battery

The temperature of the battery pack

The remaining useful life and overall condition of the battery
