Choice of Electrical Drives: Choice of Electrical Drives depends on a number of factors. Some of the important factors are: Steady state operation requirements: Nature of speed torque characteristics, speed…
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…
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…
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…
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…
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…
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…
Structure of Power System of Energy Electric System: An Structure of Power System, even the smallest one, constitutes an electric network of vast complexity. The one factor that determines the…
