Question: What is the effect of increasing the frequency of an AC source on the inductive reactance of a circuit?

Options:

Correct Answer: It increases

Solution:

Inductive reactance (XL) is given by XL = 2πfL, so increasing the frequency (f) increases the inductive reactance.

What is the effect of increasing the frequency of an AC source on the inductive reactance of a circuit?

Step 1: Understand what inductive reactance (XL) is. It is a measure of how much a coil (inductor) resists the flow of alternating current (AC).
Step 2: Know the formula for inductive reactance: XL = 2πfL. Here, 'XL' is the inductive reactance, 'f' is the frequency of the AC source, and 'L' is the inductance of the coil.
Step 3: Identify the relationship between frequency and inductive reactance. In the formula, XL is directly proportional to frequency (f).
Step 4: Realize that if you increase the frequency (f) of the AC source, the value of XL will also increase because they are connected by multiplication.
Step 5: Conclude that increasing the frequency of the AC source leads to an increase in the inductive reactance of the circuit.
