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.
on air pollution
gravitational potential energy = integral of force with respect to displacement. Find height to drop 59g egg so that it just misses touching ground.
The atmospheric pressure at any position is numerically similar to the weight of a column of air of unit cross-sectional area extending from that position to the top of the atmosph
In free space electric field intensity is provided as E= y 20 cos (ωt-50x) volt/m. Determine displacement current density.
Inductors: Coils which are used for their opposition to current change in a circuit are known as inductors or chokes. CONSTRUCTION Inductors with an air core have small
What is a good physics project?

Verify the principle of working of a cyclotron. Write two uses of this machine. Draw a labelled ray diagram of a reflecting type telescope. Write it's any one benefit over refra
Q. Why can a DC ammeter not read AC? a) Dc ammeter can't measure ac because ac is changing continuously and periodically as well as a dc ammeter can just measure a constant cur
