How is that circuit wont be broken even there is an air gap in between the parallel plates?Ans) In AC circuit capacitor offers resistance to current as aresistor would do in DC. But for DC there exists a current in between the plates called displacement current (it exists everywhere in fact)Id = ε0x dΦe/dtModified amperes law = integral of B.dl = mu0 ( I + Id)there exists a magnetic field between the plates responsible for transfer of charges from one plate to another and hence I= 0but Id is not 0. At every Id = I
Measuring with a Micrometer Caliper A simple animation of using a micrometer to measure the width of a pencil.
These capacitors are made using vitreous enamel on mixture of silica, alkali oxides and fluorides as dielectrics. These capacitors are formed by spraying vitreous lacquer on metal
Newtons Laws Skydiving Assume the motion of the skydiver below. As the skydiver falls and he encounters the force of air resistance. An amount of air resistance is dependent up
There are two parts of Thermionic emitters:- A) Directly heated emitter (i) Cathode is directly heated by passing current. (ii) Thermionic current is less. (iii) Ener
Properties of Lines of Flux To make the imaginary lines of flux describe the behaviour of the magnetic field we must give them appropriate properties. Thus lines of flux have
With the help of a bb diagram, define the principle of an optical communication system. Give its two advantages over cable communication system
Work is equal to which of the following? a) The cross product of force and displacement. b) The product of force times time c) Force divided by time d) The dot
Stretch the fingers and thumb of right hand at right angles to one another. Then if the fingers shows in the direction of field and thumb in the direction of current i, then normal
What are Newton s laws of motion? 1. A body at rest will stay at rest and one in motion will stay in motion, unless and unless acted upon by an external force. (Law of inertia)
