Production Line Interview Questions and Answers

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

• They consist of two coils of wire wrapped around a magnetic core.

• The coil that receives the electrical energy is called the primary coil, while the coil that delivers the energy is called the secondary coil.

• Transformers are used in power distrib...read more

Rectifiers convert AC to DC. Types include half-wave, full-wave, bridge, and center-tap. Used in power supplies and electronics.

• Rectifiers are electronic devices that convert AC to DC.

• Half-wave rectifiers only allow half of the AC waveform to pass through, resulting in a pulsating DC output.

• Full-wave rectifiers allow both halves of the AC waveform to be used, resulting in a smoother DC output.

• Bridge rectifiers use four diodes to convert AC to DC.

• Center-tap rectifiers use a ce...read more

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

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

• They are measured in ohms (Ω)

• Resistors can be fixed or variable

• Examples of resistors include carbon composition, metal film, and wire wound resistors
