We all know what happens when we turn on a torch or plug in a fan—the device starts working as soon as we flip the switch. But have you ever wondered why the current starts flowing, and how it relates to the voltage we apply? Let’s break down the relationship between current and voltage using […]

Complex Numbers Complex numbers are the numbers of the form $a+ ib$ where $i= \sqrt {-1}$  and a and b are real numbers Algebra for i $i= \sqrt {-1}$$i^2= -1$$i^3 =i \times i^2= -i$$i^4= i^2 \times i^2 = 1$$i^{4n} =1$$i^n + i^{n+1} + i^{n+2} + i^{n+3} =i^n( 1 + i +i^2 + i^3 ) =

Types of Carbohydrates: Carbohydrates are usually divided into the following classes: Monosaccharide: Monosaccharides are the simplest carbohydrates and the building blocks of the more Complex carbohydrates. Sugar containing 3-6 carbons atoms are known as monosaccharides. They may exist in a open chain (mostly from 3 to 5 carbon) or in a ring chain configuration (more

Examination time is intense, with many students dedicating themselves to round-the-clock study sessions to achieve high scores and move up to the next class. While it’s crucial to put in the effort, it’s equally important to manage exam-related stress effectively. Remember, it’s just an exam at the end of the day! Here are some practical

Sequence It means an arrangement of number in definite order according to some rule Important Points Arithmetic Progression An arithmetic progression is a sequence of numbers such that the difference of any two successive members is a constant a, a+ d, a+2d. a+ 3d Important formula 1. How to Prove if the sequence is AP
