The metal oxide semiconductor FET (MOSFETS): MOSFETS are another type of unipolar transistors which are similar, in many respects, to JFETS. MOSFETS also have drain, source and gate terminals similar to JFETS. Here also, the voltage across gate-source terminals contains the drain current. The only difference is that the gate terminal in a MOSFET is insulated from its channel region by using metal oxide. There are two types of MOSFETS.  They are:         I.           ...

Reverse bias: A diode is said to be reversed biased if the p-region is connected to the negative terminal and n-region is connected to positive terminal of the battery. In a reversed biased diode, the depletion region of the n-type material will increase due to the large number of free electrons drawn to the positive potential of the applied...

After the experimental discovery of electromagnetic waves by hertz in 1888, many other electromagnetic waves were discovered by different ways of excitation. The orderly distribution of electromagnetic radiations according to their wavelength or frequency is called the electromagnetic spectrum. Electromagnetic spectrum has a very wide range...

A bar magnet strongly attracts an iron piece, but other materials are weakly attracted and some are actually repelled. We may use this response of material to the field of a bar magnet to broadly classify magnetic materials. All magnetic are classified into three categories. These are: diamagnetic, paramagnetic and ferromagnetic materials....

Free oscillations: when a body capable of oscillation is displaced from its equilibrium position and then left free, it begins to oscillate with a definite amplitude and frequency. If the body is not resisted by any kind of friction, the motion continues. Such oscillation is called the free oscillation. The frequency of vibration depends...

Light is a form of energy which on entering our eyes gives the sensation of sight, and enables us to see various objects. Since the early times, scientists have made discussion on the true nature of light and have postulated various theories. These are discussed below:A.      Newton’s corpuscular theory: Newton,...
