Diodes work as a Rectifier Diode as a Rectifier: The main application of p-n junction diode is in rectification circuits. These circuits are used to describe the conversion of a.c signals to d.c in power supplies. Diode rectifier gives an alternating voltage which pulsates in accordance with time. The filter smoother the pulsation in the Read more about Diodes work as a Rectifier[…]
Maxima and Minima Maximum: Let f (x) be function with domain D ⊂ R then f (x) is said to attain the maximum value at a point a ϵ D if f (x) ≤ f (a) ∀ x ϵ D. The point is called the point maximum f (a) is known as Maximum value of Read more about Maxima and Minima[…]

Geometrical Interpretation of definite Integral If f(x) > 0 for all x ϵ [a, b] then is numerical equal to the area bounded by the curve y = f(x) then x-axis and the straight lines x = a and x = b. = Area LAMB. In general, represented an algebraic sum of the areas of Read more about Geometrical Interpretation of definite Integral[…]
Series and Parallel Capacitors When capacitors are connected in series the total capacitance is less than any one of the series capacitors’ individual capacitance. If two or more capacitors are connected in series the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacing’s of the individual capacitors. Read more about Series and Parallel Capacitors[…]
Forces between Multiple Charges Charge is an inherent property of every atom, an atom is said to be charged if it has irregular number of electrons and protons, an atom is said to be positively charged if it has less number of electrons than protons, and negatively charged if it has more number of electrons Read more about Forces between Multiple Charges[…]
Evaluation of definite Integrals If f(x) is a continuous function defined on [a, b] then to evaluate , we use the following algorithm. Algorithm: Step I: Find a primitive or anti derivative of f(x) by computing . Let this be ф(x). Step II: Compute the values ф(x) at x = a, x = b. Step Read more about Evaluation of definite Integrals[…]
Area between a Curve and Axis (i) The area bounded by the curve y = F(x) above the X-axis and between the lines x = a, y = b is given by ∫ₐb y dx = ∫ₐb F (x) dx. (ii) If the curve between the lines x = a, x = b lines below Read more about Area between a Curve and Axis[…]
Motional EMF When a conductor is moved across a magnetic field, a potential difference is setup across its ends. This potential difference is called ‘Motional EMF’. Consider the bar in the figure below. It has length l and moves at speed v to the right in magnetic field B, which is directed into the page. The field exerts a magnetic force Read more about Motional EMF[…]
