Power Factor by Two Wattmeter Method: When we talk about the power factor in three-phase circuits, it applies only to balanced circuits, since the power factor in a balanced load…
Power Measurement in Single Phase Circuit by Wattmeter: Wattmeters are generally used to measure power in the circuits. A wattmeter principally consists of two coils, one coil is called the…
Polyphase System: In an ac system it is possible to connect two or more number of individual circuits to a common polyphase source. Though it is possible to have any…
Impedance and Phase Angle of Series Resonant Circuit: The impedance of a Series Resonant Circuit is The variation of XC and XL with frequency is shown in Fig. 8.4. At…
Maximum Power Transfer Theorem: Here, the maximum power transfer theorem has been discussed for resistive loads. The maximum power transfer theorem states that the maximum power is delivered from a…
Apparent Power and Power Factor: Apparent Power - The power factor is useful in determining useful power (true power) transferred to a load. The highest power factor is 1, which…
Driving Point Function and Transfer Function: For a given network, the ratio of Laplace transform of the source voltage and source current is called driving point function. If it is…
Definition of Laplace Transform: Here we are going to discuss one of such transform methods called Laplace Transform Method which transforms the time domain differential equations to the frequency domain.…
