Sinusoids And Phasors

Sinusoids are defined as the mathematical waveforms that are used to describe the nature of periodic oscillations.

Circuit Theory

Electric circuits are a network that comprises of a closed-loop, which helps in providing a return path for the current through a switch. When the switch is activated, the load operates, and the current accepts a path to finish the circuit at a low potential level from the opposing high potential level. Electric circuits theory is a linear analysis that helps in establishing a linear relation of voltage and current for R (resistance), L (inductance), and C (capacitance).

Inductors are fundamental components in electronics and electrical circuits. They are passive devices that store energy in the form of a magnetic field when crossed by an electric current. Inductors consist of a wire wound around a core, often made of iron or another ferromagnetic material. The storage of magnetic energy in inductors is expressed in terms of inductance, measured in henries (H). What is the value of inductive reactance (XL) in ΩΩ, exhibited by the inductor in the circuit below?
