What is the formula to calculate total capacitive reactance?

The formula for calculating total capacitive reactance is given by X_C = 1 / (2 * pi * f * C), where X_C represents capacitive reactance, f is the frequency in hertz, and C is the capacitance in farads.

This equation reflects the relationship between capacitive reactance, frequency, and capacitance. As frequency increases, the capacitive reactance decreases, meaning that higher frequency signals can pass more easily through a capacitor. Conversely, a larger capacitance value will also lead to lower capacitive reactance.

Understanding this concept is essential for analyzing circuits containing capacitors, as it helps predict how the circuit will respond to alternating current (AC) signals. Capacitors are reactive components, and their behavior is crucial for applications such as filtering, timing, and energy storage in electrical systems.

The other options do not accurately represent the relationship needed to find total capacitive reactance in an AC circuit involving capacitors.
