WebExample 1: A capacitor on a computer motherboard is known to have capacitance of 5 Farads and the voltage is known to be 50 mV. What is the capacitor's charge in Farads? Since a 1 Coulomb = 1 Farad-Volt we first convert 50 mV to 0.050 V and then apply the capacitor charge equation C = Q · V = 5 · 0.050 = 0.25 C.

WebChoosing a capacitor C and frequency f is best. Capacitive reactance (symbol XC) is a measure of a capacitor's opposition to AC (alternating current).
