Reactance is defined as:

Reactance is indeed defined as the opposition to alternating current (AC) flow presented by inductors (coils) and capacitors. This opposition occurs due to the relationship between voltage and current in AC circuits, which differ from direct current (DC) circuits.

In inductors, reactance arises because the changing current induces a magnetic field, which creates a back electromotive force (EMF) that opposes the change in current. This back EMF means that more voltage is required to push the same current through the inductor, thus creating a reactive component of opposition.

In capacitors, reactance results from the capacitor charging and discharging as AC flows through it. During the charging phase, the current is temporarily drawn away from the voltage source, which causes the capacitor to delay the current phase relative to the voltage phase, leading to reactance.

While resistance refers to opposition caused by resistors and is measured in ohms, reactance can also be measured in ohms but specifically refers to how the coils and capacitors behave in AC circuits. Therefore, it is crucial to differentiate between resistance and reactance when analyzing an AC circuit because they both contribute to the overall impedance, but in different ways. Understanding reactance is essential for
