Capacitors can be arranged in two simple and common types of connections, known as series and parallel, for which we can easily calculate the total capacitance. These two …
The diffusion capacitance C D of a diode can be calculated using the formula: The diffusion capacitance C D of the diode under the given conditions is approximately 384.6 nF (nanofarads). This represents the capacitance due to the storage of charge carriers in the diode when it is forward-biased, impacting how quickly the diode can respond to changes …
Practical Example of Using the Capacitor Size Calculator Consider a single-phase motor with a power of 1000W, voltage of 230V, power factor of 0.8, and frequency of 50Hz. Inputting these values into the calculator using the formula, we find the appropriate capacitor
The resonant frequency for a RLC circuit is calculated from Equation 15.17, which comes from a balance between the reactances of the capacitor and the inductor. Since the circuit is at resonance, the impedance is equal to the resistor.
