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 …
A process called resistor color coding is used to determine the value of resistance for a resistor, just as shown in the below figure. A resistor is coated with four color bands where each color determines a particular value. The below table shows a list of values which each color indicates. The first two colored …
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 …
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 …
