These are water filters very popularly used in homes and hotels. This filter operates with the help of electricity. The device uses a porcelain filter, charcoal and UV rays to purify the wate..

Numerical 01 - In an intrinsic semiconductor, the energy gap E g is 1 eV. Its hole mobility is very much smaller than electron mobility and is independent of temperature. What is the ratio between conductivity at 600 K and that at 300 K? Assume that the temperature dependence of intrinsic..

The lifetime of certain kinds of electronic devices have a mean of 350 hours and a standard deviation of 20 hours. The distribution is measured to the nearest hour and can be approximated closely to a normal curve. What percentage of electronic devices will h..

Properties of solids have been exploited for various new innovations in electronic and magnetic devices like transistors, computers, telephones etc. Properties of the solids mainly depend upon their structure and composition. Three main properties are discussed belo..

In a chemical reaction there is a rearrangement of particles. This rearrangement of particles, results in drastic changes in the properties of the substances. For e.g., sodium and chlorine are very reactive elements. When they combine, an electron is shifted from the sodium atom to the ch..

The application of Boolean algebra to electronic devices such as computers, lies in the restriction of the variable to two possible condition 'On and Off' or 'True or False' or numerically '1 or 0'. The electric circuits carry out the Boolean logi..

The application of Boolean algebra to electronic devices such as computers, lies in the restriction of the variable to two possible condition 'On and Off' or 'True or False' or numerically '1 or 0'. The electric circuits carry out the Boolean logic. In practice, electronich..

Calculations of electric field intensity are of tremendous importance due to the technological applications of electric forces. To determine the trajectories of electrons in a T.V. tube, in an accelerator used in cancer radiotherapy, or of charged particles in a semiconductor electro..

It is seen that energies of free electrons in n type are slightly less than that of free electron in lowest energy level in conduction band. The energy 0.05 eV is comparable to the thermal energy of electron and so a very small energy is supplied to excite el..

1) They are used in the form of their alloys such as misch metal or pyrophoric alloys. 2) Their alloys are used in making traces bullets, cigarette and gas lighters. 3) Magnesium mixed with 3% misch metal is used in making jet engine parts. 4) The compounds of lanthanides are used in making magnet..
