 Spherical Capacitor

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.

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

Area of a Triangle The area of a triangle, whose vertices are (x₁, y₁), (x₂, y₂), and (x₃, y₃) is = ½ |x₁ (y₂ – y₃) + x₂ (y₃ – y₁) + x₃ (y₁ – y₂)|. Proof: Let ABC be a triangle whose vertices are A (x₁, y₁), B (x₂, y₂), and C (x₃, y₃). Read more about Area of a Triangle[…] Conversion of a Galvanometer into Voltmeter

Conversion of a Galvanometer into Voltmeter A voltmeter is an instrument used to find the potential difference across any two points in a circuit. A galvanometer can directly measure small potential differences only. To measure high potential differences, we have to do some modifications in the galvanometer. What we get after modifications is known as Read more about Conversion of a Galvanometer into Voltmeter[…] Goa Common Entrance Test (GCET) 2020 Exam Dates Released

Ammeter A galvanometer can’t be used directly to measure big currents. To measure large currents, we have to carry out some modifications in the galvanometer. What we get after modifications is known as ammeter. An ammeter is a device for measuring the electric current through a wire or a circuit element. The current is the Read more about Ammeter[…] Vector Along the Bisector of Given Two Vectors

Vector Along the Bisector of Given Two Vectors We know that the diagonal in a parallelogram is not necessarily the bisector of the angle formed by two adjacent sides. However, the diagonal in a rhombus bisects the angle between the two adjacent sides. Consider vectors and forming a parallelogram ABCD as shown in figure. Consider Read more about Vector Along the Bisector of Given Two Vectors[…]
