WebIf the transmission line is lossless, the characteristic impedance is a real number. In a lossless transmission line, only purely reactive elements L and C are present and it provides an input impedance that is purely resistive. Characteristic impedance is an important parameter to consider in both lossless and lossy transmission lines. WebWe already know that purely reactive components (or purely reactive circuits) do not dissipate power. We also know that a purely reactive impedance has an angle of +90° or –90°. How are these two facts related? Well, consider the following plot: Figure 1. Graphical representation of the relationship between voltage, current, and power.

WebNov 14, 2016 · Type I AI: Reactive machines. The most basic types of AI systems are purely reactive, and have the ability neither to form memories nor to use past experiences to inform current decisions. WebMay 22, 2024 · Similarly, if the load is purely reactive then \(\theta \) is \(\pm\)90 degrees, and Equation \ref{7.3} reduces to Equation \ref{7.2}. While this analysis used an inductive load, the same can be said regarding the capacitive case (simply swap the labels for the current and voltage waveforms). WebReactive Power of Three phase Load. Reactive power (Q) Q =Voltage x Current out of phase with the voltage. = √3V x ISinΦ. = √3 V I SinΦ. The apparent power is the vector sum of the active and the reactive power. For single phase supply system apparent power drawn cam be expressed by the following mathematical expression. cool solution refrigeration limited
