What is the effect of increasing the frequency of the AC supply on the inductive reactance? (2020)

Step 1: Understand what inductive reactance (X_L) is. It is the opposition that an inductor offers to the flow of alternating current (AC).
Step 2: Know the formula for inductive reactance: X_L = 2πfL, where 'f' is the frequency of the AC supply and 'L' is the inductance.
Step 3: Identify that in the formula, 'f' (frequency) is directly proportional to X_L (inductive reactance).
Step 4: Realize that if you increase the frequency (f), the value of X_L will also increase because they are related by multiplication.
Step 5: Conclude that increasing the frequency of the AC supply results in an increase in inductive reactance.
