Yes Bank Interview Questions and Answers

A unit is a standard measurement used to quantify physical quantities. Current is measured in amperes (A) and voltage is measured in volts (V).

• A unit is a fixed quantity used as a standard of measurement.

• Current is the flow of electric charge in a circuit and is measured in amperes (A).

• Voltage is the electric potential difference between two points in a circuit and is measured in volts (V).

• The unit of current, ampere, is named after the French physicist André-Marie Ampère.

• The...read more

Current and voltage are two fundamental concepts in electricity. Current is the flow of electric charge, while voltage is the potential difference that drives the flow.

• Current is the rate of flow of electric charge, measured in amperes (A).

• Voltage is the force or pressure that pushes the electric charge to flow, measured in volts (V).

• Current flows through a conductor, while voltage exists across a conductor.

• Current is analogous to the flow of water in a pipe, while voltage is...read more

There are several types of transformers used in electrical systems.

• Power Transformers

• Distribution Transformers

• Instrument Transformers

• Auto Transformers

• Isolation Transformers

• Step-up and Step-down Transformers

• Three-phase Transformers

Mcb stands for Miniature Circuit Breaker and MCCB stands for Molded Case Circuit Breaker.

• Mcb is a type of circuit breaker that is used for low voltage applications.

• MCCB is a type of circuit breaker that is used for high voltage applications.

• Both Mcb and MCCB are used to protect electrical circuits from overloads and short circuits.

• Mcb is usually rated for currents up to 100 amps, while MCCB can handle currents up to 2500 amps.

• Examples of applications for Mcb include residenti...read more

D.OL starter is a type of motor starter used to start and stop three-phase motors.

• D.OL stands for Direct-On-Line.

• It is the simplest and most common type of motor starter.

• It directly connects the motor to the power supply, providing full voltage to the motor.

• It is suitable for small to medium-sized motors.

• It does not provide any protection against overloading or short circuits.

• It is commonly used in applications such as pumps, fans, and conveyors.
