What is the effect of frequency on the inductive reactance? (2023)
Step 1: Understand what inductive reactance is. It is the opposition that an inductor offers to the flow of alternating current (AC).
Step 2: Know that inductive reactance is represented by the formula: XL = 2πfL, where XL is the inductive reactance, f is the frequency, and L is the inductance.
Step 3: Identify that frequency (f) is how often the current changes direction in one second, measured in hertz (Hz).
Step 4: Observe the relationship in the formula: as frequency (f) increases, the value of XL (inductive reactance) also increases.
Step 5: Conclude that if you increase the frequency of the AC signal, the inductive reactance will also increase, meaning the inductor will oppose the current flow more.
