WebMay 22, 2024 · Unsurprisingly, we call this characteristic reactance and denote it with the letter X. Reactance, like resistance, is a ratio of voltage to current. We define capacitive reactance as: (1.5.1) X C = v c i c. Using a simple sine wave with a peak value of unity, v c = sin 2 π f t, i c can be found from i = C d v / d t. WebWhat is capacitive reactance? Capacitive reactance is the opposition to the flow of alternating current by the capacitance of an electrical circuit. It is measured in Ohms, but it is not exactly the same as electrical resistance, which is also measured in Ohms. Capacitive reactance affects both the amplitude and phase of an electrical current.

Electrical Reactance: What is it? (Inductive & Capacitive)

WebJust like resistance, the value of reactance is also measured in Ohm’s but is given the symbol X, (uppercase letter “X”), to distinguish it from a purely resistive value. As the component we are interested in is an inductor, the reactance of an inductor is therefore called “Inductive Reactance”. WebThe imaginary part is called "Reactance", and L and C are called "reactive elements". Reactance is the ratio of V/I, so it has the units of Ohms, just like resistance. The impedance of an inductor is Z = jwL. The reactance of an inductor is the imaginary part, wL. To get the reactance you multiply frequency (w) times Henrys to get Ohms of ... ctl site army
