A certain capacitor has a capacitance of 3m A capacitor of 2.5mF is required by combining this capacitance with another. Calculate the capacitance of the second capacitor and state how it must be connected to the first. A 5mF capacitor is charged so that the voltage between its plates is 800V. Calculate how long the capacitor can provide an average discharge current of 2mA. Capacitances of 1µF, 3µF, 5µF and 6µF are connected in parallel to a direct voltage supply of 100V. Determine: the effective circuit capacitance the total charge
