Question: What is the effect of increasing the capacitance in a capacitor in an AC circuit on the current?

Options:

Correct Answer: Increases current

Solution:

Increasing the capacitance (C) decreases the capacitive reactance (X_C), which increases the current (I) in the circuit.

What is the effect of increasing the capacitance in a capacitor in an AC circuit on the current?

Step 1: Understand what a capacitor is. A capacitor stores electrical energy in an electric field.
Step 2: Know that in an AC (Alternating Current) circuit, the capacitor reacts to the changing current.
Step 3: Learn about capacitive reactance (X_C). This is the opposition that a capacitor offers to the flow of AC current.
Step 4: The formula for capacitive reactance is X_C = 1 / (2 * π * f * C), where f is the frequency of the AC signal and C is the capacitance.
Step 5: If you increase the capacitance (C), the value of X_C decreases because they are inversely related.
Step 6: When the capacitive reactance (X_C) decreases, it allows more current (I) to flow through the circuit.
Step 7: Therefore, increasing the capacitance in an AC circuit results in an increase in the current.
