Inductive Reactance and Capacitive Reactance
Inductive Reactance (X L) Definition: Inductive reactance is the opposition offered by the inductor in an AC circuit to the flow of AC current. It is represented by (X L) and measured in ohms (Ω). Inductive reactance is mostly low for lower frequencies and high for higher frequencies. It is, however, negligible for steady DC current.
Capacitor and inductors
We continue with our analysis of linear circuits by introducing two new passive and linear elements: the capacitor and the inductor. All the methods developed so far for the analysis of linear resistive circuits are applicable to circuits that contain capacitors and inductors. Unlike the resistor which dissipates energy, ideal capacitors and
Energy Stored in an Inductor | Electrical Academia
Figure 2 Energy stored by a practical inductor. When the current in a practical inductor reaches its steady-state value of Im = E/R, the magnetic field ceases to expand. The voltage across the inductance has dropped to zero, so the power p = vi is also zero. Thus, the energy stored by the inductor increases only while the current is building up

Difference between Capacitor and Inductor
One of the main differences between a capacitor and an inductor is that a capacitor opposes a change in voltage while an inductor opposes a change in the current. Furthermore, the inductor stores energy in the form of a magnetic field, and the capacitor stores energy in the form of an electric field. In this article, learn more differences

Both of the components are extensively used in several applications related to AC systems, especially in signal filtering.

Furthermore, capacitor stores energy in

Two other important concepts are that of an E field (measured in volts per meter) and that of a B field (a magnetic field associated with current flow).

Inductance
Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The electric current produces a magnetic field around the conductor. The magnetic field strength depends on the magnitude of the electric current, and follows any changes in the magnitude of the current. From Faraday''s law of
