Q
Q: If the frequency of an AC source is increased, what happens to the inductive reactance? (2019)
Solution:
Inductive reactance (X_L) is directly proportional to frequency (f). Therefore, if frequency increases, X_L decreases.
Steps: 4
Show Steps
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 = 2 * π * f * L, where f is the frequency and L is the inductance.
Step 3: Observe that in the formula, X_L is directly proportional to frequency (f). This means that if frequency increases, X_L will also increase.
Step 4: Conclude that if the frequency of the AC source is increased, the inductive reactance (X_L) will also increase.
