Statement of Green’s theorem Green’s theorem is the extension of Stoke’s theorem and the divergence theorem. According to this theorem, if ϕ and ψ be the scalar functions, then Proof of Green’s theorem Let a vector According to the divergence theorem. Substituting the value of eqn. (2) in eqn. (1) we get Which is the … Read more
Divergence and Curl of magnetic field Divergence of Magnetic Field We know, the magnetic field produced by a current element Id L vector at a point P (x,y,z) whose distance from the current element r is given by Therefore, the magnetic field at P due to the whole current loop is given by Taking divergence … Read more
Ampere’s circuital law has many applications in calculating magnetic field at any point due to current-carrying wire, current-carrying solenoid, and toroid. Application of ampere’s circuital law Ampere Circuital Law has basically 3 major applications: Magnetic field due to a current carrying long wire Magnetic field at a point outside the wire A current carrying long … Read more
Stokes Theorem Statement According to this theorem, the line integral of a vector field A vector around any closed curve is equal to the surface integral of the curl of A vector taken over any surface S of which the curve is a bounding edge. Stokes Theorem Proof Let A vector be the vector field … Read more
In cyclic accelerators, particles move in a circle until they acquire sufficient high energy. Examples of such accelerators are cyclotron, betatron, synchro-cyclotron, synchrotron, proton synchrotron. Construction and Working of a Cyclotron What is cyclotron ? It is a device designed by Lawrence and Livingston in 1931 to accelerate heavy particle charged particles (like proton, deuteron, … Read more
These are the basic, difference between the n-type and p-type semiconductor Sr. No. P-type Semiconductor N-type Semiconductor 1. A p-type semiconductor is formed by adding a III group element as a doping element. In an n-type semiconductor, the V group element is added as a doping element. 2. An impurity added creates a vacancy of … Read more
9 basic difference between rheostat and potentiometer Sr. No. Potentiometer Rheostat 1. A potentiometer is an instrument or component in electronics that is used to compare or measure the potential difference. A rheostat is known as a variable resistor and is used to control current or vary the resistance of a circuit. 2. A … Read more
An air conditioner Capacitor fails is a major problem in the summer season. Before fixing this problem we need to know about “what does a capacitor do in an air conditioner” In terms of AC breakdowns, one of the major common causes is a faulty AC capacitor. Capacitors are an important part of each air … Read more
Voltmeter measure the difference in the electrical potential between two places, such as two points within a circuit. A voltmeter is two terminals device, one connected to wires another to leads. When we place the one tip of lead at one of the points to be tested and the other tip at the other point … Read more
