What is the reactance of an inductor in an AC circuit with frequency f? (2023)
Step 1: Understand that reactance is a measure of how much an inductor resists the flow of alternating current (AC).
Step 2: Know that the formula for the reactance of an inductor (X_L) is X_L = 2πfL.
Step 3: Identify the variables in the formula: 'f' is the frequency of the AC signal in hertz (Hz), and 'L' is the inductance of the inductor in henries (H).
Step 4: To find the reactance, you need to multiply 2 by π (approximately 3.14), then multiply that result by the frequency (f) and the inductance (L).
Step 5: Plug in the values for frequency and inductance into the formula to calculate the reactance.
