What is the effect of increasing the capacitance in a capacitive AC circuit on the current? (2022)

Step 1: Understand that in an AC circuit, current (I) is affected by voltage (V) and reactance (Xc).
Step 2: Know that reactance (Xc) for a capacitor is calculated using the formula Xc = 1/(2πfC), where f is the frequency and C is the capacitance.
Step 3: Realize that if you increase the capacitance (C), the reactance (Xc) decreases because they are inversely related.
Step 4: Since current (I) is calculated as I = V/Xc, a decrease in Xc (due to increased capacitance) means that the current (I) will increase.
Step 5: Conclude that increasing the capacitance in a capacitive AC circuit results in an increase in the current.
