Understanding ESR and ESL in Capacitors
Because of this the input capacitor and the output filter capacitors need to be in low ESR value so that the Low-frequency ripples has no effects in the overall performance of the power supply unit. The ESL of the capacitors also needs to be low, so that the impedance of the capacitor does not interact with the power supply switching …
RMS Current Calculator, Formula, RMS Calculation
RMS values allow for direct comparison between AC and DC circuits. An AC current with an RMS value of I RMS will deliver the same power to a resistive load as a DC current of I RMS. RMS current, I RMS(A) in amperes is calculated by dividing the average power, P ave(W) in watts by voltage, V (V) in volts. ...

Therefore, it depends on the load what value you need for a capacitor. You can calculate the capacitance needed for the capacitor …
8.2: Capacitance and Capacitors
Capacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a consequence of Equation ref{8.4}.
Calculating ESR of a capacitor
When it comes to electrolytic capacitors, you may not calculate the ESR but measure it instead. As the frequency increases, the Z of the capacitor increases as the effect of (a.k.a. ESL) increases. As …
