Electrician Trainee Interview Questions and Answers

A circuit for a ballast-ignitor-capacitor-lamp is used to start and regulate the flow of electricity to the lamp.

• The ballast limits the current to the lamp

• The ignitor provides a high voltage pulse to start the lamp

• The capacitor helps regulate the current and voltage to the lamp

• The lamp is the load that produces light

• Example: A fluorescent lamp circuit with a magnetic ballast, starter, capacitor, and lamp

Star delta starter reduces starting current for three-phase motors, improving efficiency and reducing stress on electrical components.

• Used for three-phase induction motors to reduce starting current.

• Initially connects in star configuration, then switches to delta after a set time.

• Reduces mechanical stress on motor components during startup.

• Commonly used in large motors, e.g., in industrial applications like pumps and compressors.

• Control circuit includes timers and contactors ...read more
