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

Frequency dependence of dielectric constant, E lectrons have very much smal...

E lectrons have very much smaller mass than that of ions, so they respond more rapidly to a changing electric field. For electric field that oscillates at extremely high frequencie

Q Define: mobility. Give its unit. The mobility is defined as the drift velocity obtains per unit electric field. The unit of a mobility m 2 V 1s 1.

Resistors in parallel , Resistor in Parallel  Components are said to be ...

Resistor in Parallel  Components are said to be in parallel when they are connected in such a way as to provide alternative paths for current flow. The characteristics o

Relative velocity of a boat, Relative velocity of a boat in a river flowing...

Relative velocity of a boat in a river flowing at a given velocity horizontally Ans) assume the river to be stopped and measure relative velocity of boat and find angle.

Relativity principle, Relativity principle: The principle, employed th...

Relativity principle: The principle, employed through Einstein's relativity theories, that the laws of physics are the similar, at least qualitatively, in all of frames. That

The nearly-free electron model, Consider an electron in a simple one-dimens...

Consider an electron in a simple one-dimensional periodic potential. The energy of the electron will vary periodically due to the influence of the periodic potential, and can be de

Put a nail in the lower end of a candle. The nail should be just the right weight to make the candle float with its top a little above the surface of the water. Float the candle an
