A user friendly Online Educational Portal, a Mentor to the students and an Ultimate Self Assessment Platform Triangle Law of Vector Addition of Two Vectors

The physical quantities may be broadly classified into the vectors and the scalars. The quantities with magnitude and direction both are known as vector quantities, it means a vector is a physical quantity that has both magnitude and direction. If two non-zero vectors are represented by the two sides of a triangle taken in same Read more about Triangle Law of Vector Addition of Two Vectors[…] Vectors – Equation of Straight Line

Equation of Straight Line passing through a given Point and Parallel to a given Vector Vector Form: Line passing through point and parallel to vector . Let A be the given point and let AP be the given line through A. Let  be any vector parallel to the given line. Position vector of point A Read more about Vectors – Equation of Straight Line[…] Cylindrical Capacitor

Cylindrical Capacitor A cylindrical capacitor consists of two coaxial cylinders of radii a and b, say b > a. The outer one is earthed. The cylinders are long enough so that we can neglect fringing of electric fields at the ends. The electric field at a point between the cylinders will be radial, and its Read more about Cylindrical Capacitor[…] Homogeneous Differential Equation

Homogeneous Differential Equation A differential equation is said to be a homogeneous differential equation in x, y if both f (x, y), g (x, y) are homogeneous function of same degree in x and y. To find the solution of the Homogeneous Differential Equation put y = v x, then . Substituting these values in Read more about Homogeneous Differential Equation[…] Sathyabama University All India Engineering Entrance Exam (SAEEE) 2020 Notifications Released

Spherical Capacitor A spherical capacitor consists of two concentric spherical conducting shells of radii and , say . The outer shell is earthed. Place a charge on the inner shell. It will reside on the outer surface of the shell. A charge will be induced on the inner surface of the outer shell. A charge Read more about Spherical Capacitor[…] Complex Numbers – Equation of a Circle

Complex Numbers – Equation of a Circle Equation of a Circle: Consider a fixed complex number zₒ and let z be any complex number which moves in such a way that its distance from zₒ is always to r. this implies z would lie on a circle whose center is zₒ and radius is r. Read more about Complex Numbers – Equation of a Circle[…] Kirchhoff’s Rules for Capacitors

Kirchhoff’s Rules for Capacitors Kirchhoff’s rules can be used to determine the potential difference and charge on the plates of a capacitor in any electric circuit. In a circuit with capacitors and batteries, two important rules are involved. Junction Rule: A capacitor circuit obeys the principle of conservation of charge. The incoming charge at any Read more about Kirchhoff’s Rules for Capacitors[…] Remainder and Factor Theorems

Remainder and Factor Theorems Remainder Theorem: The remainder theorem states that if a polynomial f(x) is divided by a linear function x – k, then the remainder is f(k). Proof: In any division Divided = divisor x Quotient + Remainder Let Q(x) be the quotient and R be the remainder Then f (x) = (x Read more about Remainder and Factor Theorems[…] Aircraft Maintenance Engineering Common Entrance Test (AME CET) 2020 Notifications Released
