KRYFS POWER COMPONENTS Electrician Interview Questions and Answers

To convert AC to DC, a rectifier is used which converts the alternating current to direct current.

• A rectifier is used to convert AC to DC.

• There are different types of rectifiers such as half-wave rectifier, full-wave rectifier, and bridge rectifier.

• Rectifiers use diodes to convert the current.

• The rectifier circuit filters out the AC component and provides a smooth DC output.

• Examples of rectifiers include power supplies

3 phase systems typically have voltages of 208V, 240V, 480V, or 600V.

• 3 phase systems can have different voltage levels depending on the application.

• Common voltage levels for 3 phase systems include 208V, 240V, 480V, and 600V.

• The specific voltage used in a 3 phase system depends on factors such as the power requirements of the equipment being used.

• For example, a commercial building may use a 3 phase system with a voltag...read more

Mcb stands for Miniature Circuit Breaker, Rccb stands for Residual Current Circuit Breaker, and transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.

• Mcb is a type of circuit breaker that automatically switches off electrical circuits during abnormal conditions.

• Rccb is a type of circuit breaker that detects and interrupts abnormal current flow...read more

There are several types of glands in the human body.

• Endocrine glands secrete hormones directly into the bloodstream.

• Exocrine glands secrete substances through ducts.

• Examples of glands include the pituitary gland, sweat glands, and salivary glands.

Glands are used in electrical installations to provide a secure and watertight connection between cables and equipment.

• Glands prevent the entry of dust, moisture, and other contaminants into electrical enclosures.

• They ensure the safety of the electrical system by preventing short circuits and electrical shocks.

• Glands also provide strain relief, protecting cables from damage caused by pulling or twisting.

• Examples of gla...read more
