Low Frequency Response of FET Amplifier: The analysis of the Low Frequency Response of FET Amplifier is quite similar to that of the BJT amplifier. Though here common-source configuration is considered but the results can…
Low Frequency Response of BJT Amplifier: For analysis, we will consider the loaded voltage-divider BJT bias configuration. But the results can be applied to any configuration. For the network shown in Fig. 15.14 the capacitors…
Losses in Transmission Lines: Types of Losses in Transmission Lines are three ways in which energy, applied to a transmission line, may become dissipated before reaching the load: radiation, conductor heating and dielectric heating. Radiation…
Loss of Excitation Protection in Generator: Loss of excitation protection in generator can endanger the generator or the connected system or both. It is caused by accidental tripping of field breaker, short circuit in the…
Loss of Excitation Protection: Two distinct effects of Loss of Excitation Protection are that the machine starts drawing magnetizing current of large magnitude from the system, and the slip frequency emfs induced in the rotor…
Loop Tests in Underground Cables: There are several methods for locating the faults in underground cables. However, two popular methods known as Loop Tests in Underground Cables are : Murray loop test Varley loop test…
Loop Matrix or Circuit Matrix: For a given directed graph, it is always possible to state which branches are involved in the formation of loops or closed circuits or meshes. For a given oriented graph,…
Loop Analysis with Current Source or Mesh Analysis: This method of Loop Analysis is specially useful for the circuits that have many nodes and loops. The difference between application of Kirchhoff's laws and loop analysis…
Long Transmission Line Voltage: It is well known that line constants of the transmission line are uniformly distributed over the entire length of the line. However, reasonable accuracy can be obtained in line calculations for…
Long Transmission Line: For lines over 250 km, the fact that the parameters of a line are not lumped but distributed uniformly throughout its length, must be considered. Figure 5.10 shows one phase and the…
