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
explain with the aid of a diagram what is meant by the moment of a force about point
What is physics?
Gravitational field can also be shown by lines of force. This is same in several ways as that of electric lines of forces. With one dissimilarity, electric charges are negative and
In a transmitter the final stage class C amplified with 18V DC supply calculate what equivalent Road the transistor to an antenna with 50ohm load impedance design and draw an L n
A resistor is a two-terminal electrical or electronic component that resists an electric current by producing a voltage drop between its terminals in the accordance with ohm’s law.
a) A charge of 3X10 -4 Coulomb at P (1, 2, 3) and a charge of -10 -4 Coulomb at N (2, 0, 5) in a vacuum. We desire to measure the force exerted on second charge beacuse of firs
Write down the Maxwell's equation in differential form for free space.
Electrical materials: Materials which allow an electric current to flow easily are known as conductors and those which prevent the flow of an appreciable current are known as i
does lights of different wavelengths help us to see different colour
the average speed of an object over a given time duration is 6 m/s. If it travels first half of the duration with a constant speed 4 m/s, its speed during the next half duration is
