Classification of Fluids: Classification of Fluids are as follows. Ideal fluids and Real or Practical fluids. Newtonian fluids and Non-Newtonian fluids. 1 .Ideal Fluids: Ideal fluids are having following properties. It is incompressible. It has zero…
PN Junction Forward Bias: Consider the effect of an external bias voltage applied with the polarity of PN Junction Forward Bias shown in Fig. 1-23; positive on the p-side, negative on the n-side. The holes…
Reverse Bias PN Junction: When an external bias voltage is applied to a pn-junction, positive to the n-side and negative to the pride, electrons from the n-side are attracted to the positive terminal, and holes…
PN Junction Semiconductor: Two blocks of PN Junction Semiconductor material are represented in Fig. 1-17; one block is p-type material, and the other is n-type. The small circles in the p-type material represent holes, which…
P Type and N Type Semiconductor: Doping : Pure semiconductor material is known as intrinsic material. Before intrinsic material can be used for device manufacture, impurity atoms must be added to improve its conductivity. The…
Conductor Semiconductor and Insulator: Bonding Forces Between Atoms: Whether a material is a Conductor Semiconductor and Insulator depends largely upon what happens to the outer-shell electrons when the atoms bond themselves together to form a…
Conduction in Solids: Conduction in Solids or any given material occurs when an applied voltage causes electrons within the material to move in a desired direction. This may be due to one or both of…
Bandwidth Requirement in Communication System: It is reasonable to expect that the frequency range i.e., Bandwidth Requirement in Communication System for a given transmission should depend on the Bandwidth occupied by the modulation signals themselves.…
Need of Modulation in Communication System: Until the process of superimposing a low-frequency (long-wave) voice information component on a high-frequency (short-wave) carrier signal was perfected, the most widely used form of communications was a system…
Future Development of Utilization of Electrical Power: As this is being written the whole energy field is so clouded in uncertainties that it would be foolish to attempt any quantitative predictions for the future. However,…
