Dr. Reddy's Interview Questions, Process, and Tips

RCCB stands for Residual Current Circuit Breaker, a device designed to quickly disconnect power in the event of a leakage current.

• RCCB is a safety device used to protect against electric shock and fire hazards.

• It monitors the imbalance of current between the live and neutral conductors.

• If a leakage current is detected, the RCCB trips and disconnects the circuit.

• RCCBs are commonly used in residential, commercial, and in...read more

RCBO stands for Residual Current Circuit Breaker with Overcurrent Protection.

• RCBO is a type of circuit breaker that combines the functions of a residual current device (RCD) and a miniature circuit breaker (MCB).

• It provides protection against both earth faults (residual current) and overcurrents.

• RCBOs are commonly used in electrical installations to protect against electric shock and fire hazards.

• Example: A 20A RCBO wo...read more

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Consists of two coils of wire, known as primary and secondary windings

• Primary winding receives electrical energy and creates a magnetic field

• Magnetic field induces a voltage in the secondary winding, transferring energy to the load

• Used in power distribution, voltage regulation, and isola

LT HT stands for Low Tension High Tension, referring to different voltage levels in electrical systems.

• LT refers to low voltage systems typically up to 1000V, while HT refers to high voltage systems typically above 1000V.

• LT systems are commonly used in residential and commercial buildings for lighting and small appliances.

• HT systems are used in industrial settings, power distribution networks, and large machinery.

• LT HT...read more

Chromatography is a technique used to separate and analyze mixtures of chemicals based on their properties.

• Chromatography involves passing a mixture through a stationary phase, which separates the components based on their interactions with the stationary phase and mobile phase.

• Different types of chromatography include gas chromatography, liquid chromatography, and thin-layer chromatography.

• It is widely used in various...read more

Analysis is the process of examining data or information to uncover insights, patterns, and trends.

• Analysis involves breaking down complex information into smaller components for better understanding.

• It helps in making informed decisions based on the findings.

• Examples include financial analysis to assess company performance, data analysis to identify trends in customer behavior, and market analysis to understand indust
