Susceptance to Capacitance Calculator

To calculate capacitance (C) from susceptance (B), you can use the formula C = 1 / (2πfB), where f is the frequency. Susceptance and capacitance are inversely related, so as susceptance increases, capacitance decreases, and vice versa. This formula helps determine the capacitance of a capacitive component in an AC circuit based on its susceptance and operating frequency.
