Can you replace 2200 uf 24 volt capacitor with a 2200 uf 16 volt capacitor?

NO dont do it if you devalue a capacitors voltage parameter what will it do when it is face to face with 20V ? The voltage will destroy the thing. Remember it is OK for you to use a higher voltage parameter for a capacitor but never lower


If capacitors dont use ac current then how and why are they used in most appliances?

Capacitors resist a change in voltage, proportional to capacitance and current. This is called capacitive reactance. As a result, a capacitor in an AC circuit will create a leading phase angle, current relative to voltage. This, for example, can be used to help start a motor by creating two magnetic fields, one leading the other.


Does a capacitor block ac current dc current or both?

No you can't use DC capacitors in Ac because in DC current , the current flows directly while in AC current, the current flows curved zig-zag. Thus Dc equipment can't mingle with AC as they need Direct flow. So DC capacitors can't be used for AC current...................AnswerMost capacitors will operate on either DC or AC. The exception is the polarised-type capacitor, which is designed to operate with a DC or an appropriately-biased supply.Often, a capacitor's rated voltages is specified in terms of DC -for example, '100 V (DC)', so care must be exercised if it is to be used with AC. This is because we always measure AC voltages as root-mean-square (rms) values, not as peak values. For example, '100 V (AC)' actually peaks at 141 V*. So, applying 100 V (AC) to a capacitor rated at 100 V (DC) may cause its dielectric to fail. In this example, the maximum allowable AC voltage must be 70.7 V, which peaks at 100 V.(*To explain: Vrms = 0.707 Vmax )
