Options:

Correct Answer: Decreases phase angle

Solution:

Increasing capacitance decreases the phase angle between voltage and current in an AC circuit.

What is the effect of increasing the capacitance in an AC circuit on the phase angle between voltage and current?

What is the effect of increasing the capacitance in an AC circuit on the phase angle between voltage and current?

Step 1: Understand that in an AC circuit, voltage and current can be out of sync, which is measured by the phase angle.
Step 2: Know that capacitance is a property of a capacitor that affects how it stores and releases electrical energy.
Step 3: Realize that increasing capacitance means the capacitor can store more charge.
Step 4: When capacitance increases, the capacitor can respond more effectively to changes in voltage.
Step 5: This improved response causes the current to lead the voltage more closely, reducing the phase angle.
Step 6: Therefore, increasing capacitance decreases the phase angle between voltage and current.
