Solar panels generate energy from sunlight by converting sunlight into electricity through photovoltaic cells.
Solar panels use photovoltaic cells to convert sunlight into electricity
The photovoltaic cells are made of semiconductor materials like silicon
When sunlight hits the cells, it creates an electric current
This electric current is then converted into usable electricity for powering homes or devices
A battery is a device that stores chemical energy and converts it into electrical energy to power electronic devices.
Batteries come in various sizes and types, such as alkaline, lithium-ion, and lead-acid.
They are commonly used in electronic devices like smartphones, laptops, and cars.
Batteries consist of one or more cells that contain electrolytes and electrodes.
When a battery is connected to a circuit, chemical react...
Distribution of power.
Solar panels are devices that convert sunlight into electricity by using photovoltaic cells.
Solar panels are made up of photovoltaic cells that capture sunlight and convert it into electricity.
They are commonly used to generate renewable energy for residential, commercial, and industrial purposes.
Solar panels are mounted on rooftops or in open fields to maximize exposure to sunlight.
They are environmentally friendly an...
There are mainly three types of solar panels: monocrystalline, polycrystalline, and thin-film.
Monocrystalline solar panels are made from single-crystal silicon and are known for their high efficiency.
Polycrystalline solar panels are made from multiple silicon crystals and are more affordable but slightly less efficient than monocrystalline panels.
Thin-film solar panels are made by depositing a thin layer of photovoltai...

Converter test involves testing the performance and efficiency of a converter, while DFIG (Doubly Fed Induction Generator) is a type of generator used in wind turbines.
Converter test evaluates the performance of a power converter by analyzing its efficiency, power factor, and voltage regulation.
DFIG is a type of generator commonly used in wind turbines to convert mechanical energy into electrical energy.
Testing DFIG in...
I applied via Naukri.com and was interviewed before May 2023. There were 3 interview rounds.
Lifecycle methods are methods that are automatically called at certain points in the lifecycle of a component in React.
Lifecycle methods include componentDidMount, componentDidUpdate, componentWillUnmount, etc.
These methods allow developers to perform actions at specific points in a component's lifecycle, such as fetching data after the component has been rendered.
They are used to manage side effects, perform cleanup, ...
React is a popular JavaScript library for building user interfaces.
Component-based architecture for reusability and easy maintenance
Virtual DOM for efficient updates and performance optimization
JSX syntax for writing HTML within JavaScript
One-way data binding for predictable data flow
Support for server-side rendering for improved SEO
Large community and ecosystem with many third-party libraries and tools
Class components are ES6 classes that extend from React.Component and have state and lifecycle methods, while functional components are simple functions that take props as input and return JSX.
Class components are defined using ES6 classes and have a render method.
Functional components are defined as simple functions that take props as input and return JSX.
Class components can have state and lifecycle methods like comp...
Higher order components are functions that take a component and return a new component with additional functionality.
Higher order components enhance the functionality of existing components
They can be used for code reusability and separation of concerns
Examples include withRouter from React Router and connect from React Redux
React hooks are functions that let you use state and other React features without writing a class.
React hooks were introduced in React 16.8.
They allow you to use state and other React features in functional components.
Some commonly used hooks are useState, useEffect, useContext, and useReducer.
Hooks are more flexible and easier to use compared to class components.
ContextAPI is a built-in feature in React for managing global state, while Redux is a separate library for state management in React applications.
ContextAPI is built into React, while Redux is a separate library.
ContextAPI is primarily used for managing global state in a React application.
Redux provides a centralized store for state management and follows a unidirectional data flow.
ContextAPI is simpler to use for smal...
Semantic elements in HTML are tags that clearly define the content they wrap, providing meaning to both browsers and developers.
Semantic elements help improve SEO by providing search engines with better understanding of the content.
Examples of semantic elements include <header>, <footer>, <article>, <section>, <nav>, <aside>, <main>, <figure>, <figcaption>, <deta...
Pseudo elements are used in CSS to style specific parts of an element.
Pseudo elements are denoted by double colons (::) in CSS.
They allow styling of specific parts of an element, like the first letter or line.
Common pseudo elements include ::before, ::after, ::first-line, and ::first-letter.
The box model is a fundamental concept in CSS that defines the layout of elements on a webpage.
The box model consists of content, padding, border, and margin.
Content: the actual content of the element, such as text or images.
Padding: space between the content and the border.
Border: a line that goes around the padding and content.
Margin: space outside the border, separating the element from other elements.
Hoisting is a JavaScript mechanism where variable and function declarations are moved to the top of their containing scope during the compilation phase.
Variable and function declarations are hoisted to the top of their scope.
Only declarations are hoisted, not initializations.
Function declarations take precedence over variable declarations.
Example: console.log(myVar); var myVar = 10; // Output: undefined
Example: cons...
Normal functions are defined using the function keyword, while arrow functions are defined using the => syntax.
Normal functions are hoisted, while arrow functions are not hoisted.
Arrow functions do not have their own 'this' keyword, they inherit it from the parent scope.
Arrow functions do not have their own 'arguments' object.
Arrow functions are more concise and have implicit return.
Arrow functions cannot be used as co
Splice and slice are methods used in programming to manipulate arrays.
Splice is used to add or remove elements from an array at a specific index.
Slice is used to extract a portion of an array and returns a new array.
Example of splice: array.splice(2, 0, 'new element') - adds 'new element' at index 2.
Example of slice: array.slice(1, 4) - extracts elements from index 1 to 3.
Coding questions on Java script like array methods and objects handling. coding questions on React is like life cycle methods using functional components and state management.
