fixed and variable resistors

A Linear resistor is one whose resistance doesn’t vary with the flow of current through it. The current through it, will always be proportional to the voltage applied across it. Linear resistors are further classified as Fixed and Variable resistors. Variable resistors are those whose values can be varied manually, according to the requirement. A […]

intrinsic and extrinsic semiconductor

In order to increase the conduction capability of intrinsic semiconductor, it is better to add some impurities. This process of adding impurities is called as Doping. Now, this doped intrinsic semiconductor is called as an Extrinsic Semiconductor. A Semiconductor in its extremely pure form is said to be an intrinsic semiconductor. The properties of this

what is intrinsic semiconductor

A Semiconductor in its extremely pure form is said to be an intrinsic semiconductor. The properties of this pure semiconductor are as follows: The electrons and holes are solely created by thermal excitation. The number of free electrons is equal to the number of holes. The conduction capability is small at room temperature. In order
