10+ Entrepreneurs Organization Interview Questions and Answers

Three-phase supply consists of three alternating currents, while single-phase supply has only one alternating current.

• Three-phase supply is commonly used in industrial and commercial settings.

• Single-phase supply is typically used in residential applications.

• Three-phase supply provides more power and is more efficient than single-phase supply.

• Three-phase supply requires three conductors, while single-phase supply requires only two.

• Examples of three-phase devices include motors...read more

MCBs are more reliable and safer than fuses.

• MCBs can be reset and reused, while fuses need to be replaced after every trip

• MCBs have a faster response time than fuses, which can prevent damage to equipment

• MCBs have better overload protection than fuses

• MCBs are more convenient to use as they do not require replacement every time they trip

• MCBs are safer as they do not release harmful gases or debris when they trip

Current rating is not written on electrical appliances to avoid confusion and liability.

• Current rating may vary depending on the location and voltage of the appliance.

• Manufacturers may not want to be liable for incorrect usage of the appliance.

• Current rating can be found in the user manual or on the packaging.

• Some appliances may have a range of current ratings depending on the mode of operation.

• Regulations may not require current rating to be displayed on certain types of app...read more

New fan regulators are more energy-efficient and have additional features compared to old ones.

• Old fan regulators use resistors to control the speed of the fan, while new ones use electronic circuits.

• New fan regulators have additional features such as remote control, timer, and speed settings.

• Old fan regulators are less energy-efficient and can cause the fan to make noise or vibrate.

• New fan regulators are more reliable and have a longer lifespan compared to old ones.

No, UPS and inverter are not interchangeable.

• UPS is designed to provide backup power for a short duration, while an inverter is designed to provide continuous power.

• UPS typically has a built-in battery, while an inverter requires an external battery.

• UPS is commonly used for computers and other electronic devices, while inverters are used for larger appliances like refrigerators and air conditioners.

A capacitor stores electrical energy and releases it when needed.

• Capacitors are used in electronic circuits to filter out noise and stabilize voltage.

• They can also be used to store energy in flash cameras and defibrillators.

• Capacitors come in different types and sizes, with varying capacitance and voltage ratings.

• They are made of two conductive plates separated by a dielectric material.

• The capacitance of a capacitor depends on the surface area of the plates and the distance b...read more

Relay and contactor are electrical switches that control the flow of electricity in a circuit.

• Relays are used to switch smaller currents in a circuit, while contactors are used to switch larger currents.

• Relays are often used in control circuits to turn on or off devices, while contactors are used in power circuits to control motors and other high-power loads.

• Both relay and contactor have an electromagnetic coil that, when energized, pulls in a set of contacts to make or break...read more

MCB stands for Miniature Circuit Breaker, a device used to protect electrical circuits from overloads and short circuits.

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

• It is commonly used in residential and commercial buildings to protect electrical appliances and wiring.

• MCBs are available in different current ratings and trip characteristics to suit different applications.

• They are more compact and efficient tha...read more

Kafka Zookeeper plays a crucial role in managing and coordinating Kafka brokers in a distributed system.

• Zookeeper manages configuration information, leader election, and synchronization for Kafka brokers.

• It helps in maintaining the state of the Kafka cluster and ensures fault tolerance.

• Zookeeper stores metadata about Kafka topics, partitions, and replicas.

• It also helps in detecting and recovering from network partitions within the Kafka cluster.

• Overall, Zookeeper acts as a ce...read more

Program to add a node in binary tree using recursive function.

• Create a function to recursively traverse the tree to find the appropriate position to add the new node.

• Check if the current node is null, if so, create a new node and assign it to the current node.

• If the current node is not null, compare the value of the new node with the current node and move left or right accordingly.

• Repeat the process until the appropriate position is found and the new node is added.

Design a system monitoring application like Heartbeat in ELK

• Utilize Elasticsearch for storing monitoring data

• Use Logstash for collecting and parsing logs

• Implement Kibana for visualization and monitoring

• Set up Beats for lightweight data shippers

The program finds the frequency of each character in a given string.

• Create an array to store the frequency of each character (size 256 for ASCII characters)

• Iterate through the string and increment the corresponding index in the array

• Print the frequency of each character

Program to reverse a string

• Create a character array to store the reversed string

• Iterate through the original string in reverse order and populate the character array

• Convert the character array back to a string and return
