Improving power factor can be done by using capacitors, synchronous motors, and active power filters.

• Installing capacitors to reduce reactive power consumption

• Using synchronous motors to improve power factor

• Using active power filters to reduce harmonic distortion

• Implementing power factor correction techniques

• Reducing the use of inductive loads

• Proper maintenance of electrical equipment

• Educating employees on energy-efficient practices

Transformer earthing types include solid earthing, resistance earthing, and reactance earthing. The size of the transformer neutral earthing conductor depends on the transformer rating.

• Solid earthing involves connecting the transformer neutral directly to the earth

• Resistance earthing involves connecting a resistor between the transformer neutral and earth

• Reactance earthing involves connecting a reactor between the transformer neutral and earth

• The size of the transformer neutr...read more

Induction motor works on the principle of electromagnetic induction and has two types - single-phase and three-phase.

• Induction motor has a stator and a rotor

• The stator has a set of windings that are supplied with AC current

• This current creates a rotating magnetic field that induces a current in the rotor

• The rotor then starts rotating due to the interaction of the magnetic fields

• Single-phase induction motors are used in small appliances while three-phase induction motors are u...read more

AC drives are used for high power applications and DC drives are used for low power applications.

• AC drives are more efficient than DC drives.

• AC drives are more expensive than DC drives.

• DC drives are simpler and easier to control than AC drives.

• DC drives are commonly used in small motors and appliances.

• AC drives are commonly used in large motors and industrial applications.

RIP stands for Routing Information Protocol. RIPv1 is a classful routing protocol while RIPv2 is a classless routing protocol.

• RIP is a distance vector routing protocol used to exchange routing information within a network.

• RIPv1 does not support VLSM (Variable Length Subnet Masking) while RIPv2 does.

• RIPv1 broadcasts routing updates every 30 seconds while RIPv2 multicasts updates.

• RIPv1 does not support authentication while RIPv2 does.

• RIPv2 supports route tagging for better cont...read more

ACB stands for Air Circuit Breaker. It works on the principle of thermal and magnetic tripping.

• ACB is used to protect electrical equipment from overcurrent and short circuit faults.

• It consists of a set of contacts that open and close to interrupt or allow the flow of current.

• The thermal tripping mechanism operates based on the heat generated by the current flowing through the contacts.

• The magnetic tripping mechanism operates based on the magnetic field generated by the curren...read more

Various routing protocols are used in networking, such as OSPF, EIGRP, BGP, and RIP.

• OSPF (Open Shortest Path First) is a link-state routing protocol commonly used in large networks.

• EIGRP (Enhanced Interior Gateway Routing Protocol) is a Cisco proprietary protocol.

• BGP (Border Gateway Protocol) is used for routing between different autonomous systems.

• RIP (Routing Information Protocol) is a distance-vector protocol.

• The choice of routing protocol depends on the network size, comp...read more

STP is a network protocol that ensures a loop-free topology in Ethernet networks by blocking redundant paths.

• STP prevents loops in Ethernet networks by blocking redundant paths

• It selects a root bridge to serve as the reference point for the network

• STP calculates the shortest path to the root bridge for each switch

• It uses Bridge Protocol Data Units (BPDUs) to exchange information between switches

• STP can have different variants like RSTP (Rapid Spanning Tree Protocol) and MSTP ...read more

Earthing is the process of connecting the metallic parts of an electrical appliance or installation to the earth wire.

• Types of earthing include plate earthing, pipe earthing, rod earthing, and strip earthing.

• Plate earthing involves burying a plate made of copper or galvanized iron in the earth.

• Pipe earthing involves using a pipe made of GI or copper to connect the electrical appliance to the earth.

• Rod earthing involves using a rod made of copper or galvanized iron to connect ...read more

Role refers to the responsibilities and duties assigned to an individual in an organization. Running a Marwadi company requires knowledge of Marwadi culture and business practices.

• Understand Marwadi culture and business practices

• Develop a strong network within the Marwadi community

• Implement effective financial management strategies

• Maintain strong relationships with suppliers and customers

• Ensure compliance with legal and regulatory requirements

API testing is a type of software testing that involves testing APIs directly and ensuring they meet functional and performance requirements.

• API testing involves testing the functionality, reliability, performance, and security of APIs

• It can be done manually or through automated testing tools

• API testing can be done at different levels such as unit, integration, and end-to-end testing

• Examples of API testing tools include Postman, SoapUI, and JMeter

I primarily use TCP/IP protocol for networking communication.

• TCP/IP is the most commonly used protocol in computer networking.

• It is a suite of protocols that allows devices to communicate over a network.

• Examples of TCP/IP protocols include HTTP, FTP, SMTP, and Telnet.

A Test Plan is a document that outlines the testing strategy, objectives, scope, and approach for a software project.

• Test Plan defines the testing activities to be carried out on a software project

• It includes the testing objectives, scope, approach, resources, and schedule

• Test Plan helps to ensure that all aspects of the software are tested thoroughly

• It also helps to identify the risks and issues associated with the testing process

• Examples of Test Plan documents include Maste...read more
