Preview Questions Electronics Maintenance Technician | Role Specific Skill

Question 1: How would you approach the repair of a capacitor in a power circuit that has started to show signs of leakage?

Which action should you take?

Choose only one option

By replacing the capacitor and checking the circuit for other potential issues

By testing the surrounding components and then replacing the capacitor if necessary

By assuming the capacitor is the only fault and ignoring other components

By only cleaning the capacitor and continuing use

Question 2: What is the most effective way to detect degradation in insulation material during preventive maintenance?

Which action should you take?

Choose only one option

Measure input voltage

Test for continuity

Visual inspection

Measure insulation resistance using a megohmmeter

Question 3: How do you verify the effectiveness of a cooling system during preventive maintenance?

Which action should you take?

Choose only one option

Replace cooling fans without testing

Increase fan speed to maximum

Measure component temperatures and inspect for obstructions in airflow paths

Check the airflow visually

Question 4: How do you use a clamp meter for measuring current, and what is the significance of this tool in electrical testing?

Which action should you take?

Choose only one option

By measuring resistance in a circuit

By using the meter only in open circuits

By clamping the meter around one conductor to measure the current without interrupting the circuit

By directly measuring the voltage across a component

Question 5: When repairing an electric motor, what is the most likely cause of excessive noise during operation?

Which action should you take?

Choose only one option

Overvoltage supply

Loose terminal connections

Incorrect winding resistance

Insufficient lubrication of bearings

Question 6: How do you handle preventive maintenance for an embedded system with limited access to components?

Which action should you take?

Choose only one option

By assuming the system will function correctly without testing

By bypassing the system and testing components externally

By using remote diagnostics, checking power supply integrity, and verifying the firmware

By testing only the accessible components and assuming the rest are functional
