Question: What is the effect of increasing the capacitance in an AC circuit on the capacitive reactance?

Options:

Correct Answer: Decreases

Solution:

Capacitive reactance (X_C) is given by X_C = 1/(2πfC). Increasing capacitance (C) decreases X_C.

What is the effect of increasing the capacitance in an AC circuit on the capacitive reactance?

Step 1: Understand what capacitive reactance (X_C) is. It is a measure of how much a capacitor resists the flow of alternating current (AC).
Step 2: Know the formula for capacitive reactance: X_C = 1/(2πfC), where f is the frequency of the AC signal and C is the capacitance.
Step 3: Identify what happens when you increase the capacitance (C) in the formula. If C increases, the denominator (2πfC) becomes larger.
Step 4: Realize that if the denominator of a fraction increases, the overall value of the fraction decreases.
Step 5: Conclude that increasing the capacitance (C) results in a decrease in capacitive reactance (X_C).
