Question 1: In a power supply circuit, why are inductors used in conjunction with capacitors?

Which action should you take?

Choose only one option

To reduce the weight of the system

To smooth out the ripple in the output DC

To regulate temperature fluctuations

To increase the overall power output

Question 2: In troubleshooting low voltage power supplies, what is the most common cause of output failure?

Which action should you take?

Choose only one option

A short-circuit in the output lines

A faulty rectifier diode preventing proper AC to DC conversion

A blown fuse or damaged capacitor leading to voltage drop

A failure in the feedback loop causing instability in the regulation

Question 3: How would you determine the root cause of frequent fuse blowouts in an electrical circuit?

Which action should you take?

Choose only one option

Inspecting for a short circuit

Verifying current draw

Checking for loose connections

Measuring supply voltage

Question 4: When troubleshooting a circuit with excessive current draw, what is the most critical parameter to measure first?

Which action should you take?

Choose only one option

Resistance across the load

Current through each branch

Voltage across the power supply

Temperature of components

Question 5: When replacing capacitors in a circuit, what is the main factor that could affect the longevity of the replacement capacitor?

Which action should you take?

Choose only one option

The physical size of the capacitor should fit the designated slot

The rated voltage must be higher than the circuit's operating voltage

The equivalent series resistance (ESR) must match the original specification

The material of the capacitor's housing should be compatible

Question 6: How would you handle a situation where a customer is complaining about a defective product that is out of warranty?

Which action should you take?

Choose only one option

Explain the warranty terms and offer repair service at a fee

Apologize and provide a discount for future purchases

Offer a refund as a goodwill gesture

Offer a replacement for the customer with an extended warranty
