Keltron Technician Apprentice Interview Questions and Answers

Electronic components are parts that make up electronic devices and systems.

• Electronic components are used to control the flow of electricity in electronic devices.

• Examples of electronic components include resistors, capacitors, transistors, and diodes.

• Electronic components can be classified as active or passive components.

• Active components require a power source to function, while passive components do not.

A motor converts electrical energy into mechanical energy, while a generator converts mechanical energy into electrical energy.

• Motor uses electricity to produce motion, while generator uses motion to produce electricity

• Motors are commonly found in appliances, vehicles, and industrial machinery

• Generators are used in power plants, wind turbines, and backup power systems

Current is the flow of electric charge through a conductor.

• Current is measured in amperes (A)

• It is the rate of flow of electric charge

• Direct current (DC) flows in one direction, while alternating current (AC) changes direction periodically

Resistors are electronic components that limit the flow of electric current in a circuit.

• Resistors are used to control the amount of current flowing in a circuit.

• They are measured in ohms (Ω) and come in various values.

• Resistors can be fixed or variable depending on the application.

• Examples include carbon film resistors, metal film resistors, and variable resistors like potentiometers.

A diode is a semiconductor device that allows current to flow in one direction only.

• Semiconductor device

• Allows current flow in one direction only

• Commonly used in rectifiers and voltage regulators

The interviewer is asking about common problems with motor meggers.

• Common problems with motor meggers include incorrect readings due to dirty or damaged insulation, faulty connections, or incorrect test settings.

• Ensure proper cleaning and maintenance of the megger to avoid inaccurate readings.

• Check for loose or damaged connections before testing to ensure accurate results.

• Verify that the test settings on the megger are...read more

At my last company, I faced challenges with outdated equipment and limited resources.

• Outdated equipment made it difficult to efficiently complete tasks

• Limited resources hindered the ability to innovate and improve processes

• Lack of support from management in upgrading technology and tools

• Difficulty in meeting project deadlines due to these challenges
