Ampere's law, modified form:
The line integral of the magnetic field about a closed curve is proportional to the total of two terms: first one, the algebraic total of electric currents passing through that closed curve; and second one, the instant time rate of change of the electric flux by a surface limited by that closed curve; in differential form,
curl H = J + dD/dt,
where d/dt revel partial differentiation.
Additionally to defining electromagnetism, his equations also predict which waves can propagate by the electromagnetic field, and always would propagate at the similar speed these are electromagnetic waves; the speed can be determined by calculating (epsilon0 mu0)-1/2, which is c, the speed of light within vacuum.
What is splicing? Splicing: Two optical fibers utilized for communication are joined with a process termed as Splicing. This must be done very carefully that is the splicing
A vertical spring generates simple harmonic motion with period 1sec. when a mass of 1gm suspended at the lower end of the spring, calculate the length through which the spring stre
Five coulombs of charge are placed on a thin-walled conducting shell. Once the charge has come to rest, the electric potential in the hollow conducting shell is found to be:
The Law of Reflection While a ray of light strikes a plane mirror and the light ray reflects off the mirror. Reflection includes a change within direction of the light ray. The
Which of the subsequent conditions must be met in order for a uniform magnetic field to exert a force on a particle? Ans: A charged particle has to be in a magnetic ground
Displacement related with a wave is given by y (x, t) = 0.1 cos(0.2x-2t). Where x y are in cm and ‘t' in second. Determine the wavelength, amplitude, frequency and velocity.
Charging: During charging the device is linked across a source of D.C. supply having a voltage of about 3 volts. When the circuit is switched on the current flows inside the cell
