Write down the Maxwell's electromagnetic equation in differential form in a medium, in the presence of currents and charges. Identify and state the laws of electromagnetism with which these equations are related.
It is the distance travelled by the disturbance in single time period. It only relays on the properties of the medium and it independent of time and position.
Hertz; Hz (after H. Hertz, 1857-1894) The derived SI unit of frequency, explained as a frequency of 1 cycle per s; therefore it has units of s -1 .
Joule's laws (J.P. Joule) Joule's first law The heat Q generated while a current I pass through a resistance R for a particular time t is given by following Q = I2 R
EXAMPLES OF IT
A coil of 600 turns is wound uniformly on a ring of non-magnetic material. The ring has a uniform cross-sectional area of 200mm 2 and a mean circumference of 500mm. If the current
When a dielectric field is completely full in among charges rearrangement of the charges inside the dielectric medium takes place and the force among the same tow charge reduces by
A certain machine exerts a force of 200 newtons on a box whose mass is 30 kilograms. The machine moves the box a distance of 20 meters along a horizontal floor. What amount of wor
Besides solid, liquid, and gas, what is the fourth form of matter? Ans: The fourth form of matter is plasma.
If conductors carries current in similar direction, then force among them will be attractive. If conductor carries current in reverse direction, then force among them will be repul
Characteristics of Resistance in parallel: Different amount of current passing by each resistance. i.e. I = I1 + I2 + I3 + I4 ........ The potential difference across every
