10+ Ynoox Interview Questions and Answers

The timer in the Satar Delta Satar controls the switching between star and delta configurations in a motor.

• The timer is responsible for automatically switching the motor from star to delta configuration after a set time period.

• This helps in reducing the starting current and providing a smoother transition for the motor.

• For example, in a motor starting application, the timer ensures that the motor starts in star configuration for a specific duration before switching to delta c...read more

Active power is the actual power consumed by a circuit, while reactive power is the power that flows back and forth between the circuit and the source without being consumed.

• Active power is measured in watts (W) and represents the real power used to perform work in a circuit.

• Reactive power is measured in volt-amperes reactive (VAR) and represents the power oscillating between the circuit and the source due to inductive or capacitive loads.

• The combination of active power and r...read more

kW is the actual power consumed by a device, while kVA is the apparent power used by the device including reactive power.

• kW measures the actual power consumed by a device, taking into account only real power

• kVA measures the total power used by a device, including both real power (kW) and reactive power (kVAR)

• The relationship between kW and kVA is influenced by the power factor of the device

• For example, a device with a power factor of 0.8 will have a kW value lower than its kV...read more

The purpose of using and maintaining power factor is to improve energy efficiency, reduce electricity costs, and prevent equipment damage.

• Improves energy efficiency by reducing wasted energy in the system

• Reduces electricity costs by optimizing power usage

• Prevents equipment damage by ensuring proper voltage and current levels

• Helps in meeting utility requirements and avoiding penalties for low power factor

• Examples: Installing power factor correction capacitors, regular monitori...read more

The equivalent wattage of 1 horsepower is 746 watts.

• 1 horsepower is equal to 746 watts.

• This conversion is commonly used in electrical engineering and mechanical fields.

• For example, if a motor has a power rating of 2 horsepower, it would be equivalent to 1492 watts.

A kvar is a unit of reactive power in an electrical system, measured in kilovolt-amperes.

• Kvar is used to measure the reactive power in an electrical system, which is the power consumed by inductive loads such as motors and transformers.

• It is important to manage kvar to ensure efficient power factor correction and reduce energy losses in the system.

• Kvar is calculated using the formula: kvar = kVA * sin(theta), where theta is the phase angle between voltage and current.

• An examp...read more

A star-delta starter is used to reduce the starting current of induction motors.

• Reduces the starting current by initially connecting the motor in star configuration and then switching to delta configuration

• Helps in reducing voltage drops during motor starting

• Used for large induction motors to prevent damage to the motor windings

• Commonly used in industries where high-power motors are employed

The disintegration time of tablets varies depending on the type of tablet.

• Disintegration time refers to the time it takes for a tablet to break down into smaller particles in a solution.

• Different types of tablets may have different disintegration times due to variations in their composition and formulation.

• Factors that can affect disintegration time include the type and amount of excipients used, the presence of coatings or binders, and the drug release mechanism.

• For example,...read more

GMP stands for Good Manufacturing Practices, while cGMP stands for current Good Manufacturing Practices.

• GMP is a set of guidelines and regulations that ensure the quality and safety of pharmaceutical products.

• cGMP is an updated version of GMP that incorporates current industry standards and practices.

• GMP and cGMP cover various aspects of manufacturing, including facilities, equipment, personnel, documentation, and quality control.

• Adhering to GMP and cGMP is crucial for pharma...read more

GDP stands for Gross Domestic Product.

• GDP is a measure of the total value of goods and services produced within a country's borders in a specific time period.

• It is used to gauge the economic health and growth of a country.

• GDP can be calculated using three different approaches: production, income, and expenditure.

• It is often used to compare the economic performance of different countries.

• For example, the GDP of the United States in 2020 was $21.43 trillion.
