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
A circular coil has a 12.8cm radius and consists of 29.0 closely wound turns of wire. An externally produced magnetic field of magnitude 2.23 mT is perpendicular to the coil. (a) i
If 10 9 electrons move out of a given body to another body every second, how much time is required to get a total charge of 1C of the other body? ------------------------------
how much power is radiated by a tungsten sphere of radius 16cm at a temperature of 25 degrees Celsius emissivity is 0.35
Yes it is possible at the centre of the earth where the radius is zero .
A surveyor is using a magnetic compass 7.1 m below a power line in which there is a steady current of 120A. What is the magnetic field in microteslas at the site of the compass due
a) Amplitude : It is the main value of distance of the particle from its equilibrium position. b) Time period (T): Smallest time interval after which the oscillatory motion
The idea that everything is made up of very small particles has been developed over many years supported by several experiments: (i) Brownian motion :
In computing the electric field at some point P in the x-y plane of a Cartesian coordinate system due to a linear charge distribution in the x-y plane each contribution to the elec
