This heating is inevitable in any electrical circuit. Since the energy lost by the flowing charges ends up as disorderly thermal motion, the phrase 'ohmic dissipation' is also used to describe it. Often, this is an undesirable effect. For example, in electric circuits, the heat produced i..

In the physical world, one of the most common phenomena is motion. The branch of Physics, which deals with the behaviour of moving objects, is known as mechanics. Mechanics is further divided into two sections namely Kinematics and Dynamics. Kinematics deals with the study of m..

Practical Applications of Reflection of Sound - Some applications of the principle of Reflection of Sound are: (1) Megaphone, (2) Hearing Board, (3) Sound Board..

When free space is the communication channel, antennas radiate and receiver the signal. Theory shows that the antennas operate effective only when their dimensions are of the order of the magnitude of wavelength of the signal being transmitted...
