Polarized Capacitor in reverse direction??

The output capacitor to an 8Ω speaker would have to be 2200μF-4700μF if you want to achieve decent performance below 100Hz. Which way should the electrolytic capacitor be connected? "Reverse direction" is a misunderstanding. Simply, the capacitor should be connected with the +ve lead towards the more positive node of the circuit.

electricity

$begingroup$ Since the circuit is at a constant potential difference and the pulling apart of the capacitor plates reduces the capacitance,the energy stored in the capacitor also decreases. The energy lost by the capacitor is given to the battery (in effect, it goes to re-charging the battery). Likewise, the work done in pulling the plates apart is …

8.1 Capacitors and Capacitance

When reverse polarization occurs, electrolytic action destroys the oxide film. This type of capacitor cannot be connected across an alternating current source, because half of the time, ac voltage would have the wrong polarity, as an alternating current reverses its polarity (see Alternating-Current Circuits on alternating-current circuits).

What makes a capacitor polarized or non-polarized?

An electrolytic capacitor in reverse polarity should not be trusted. 2 It actually will occur under safe circumstances if you have two electrolytic capacitors "back-to-back" filtering an AC signal, ... When a capacitor is connected backwards, or "reverse-biased," it can cause problems in a circuit. If a voltage is applied to the capacitor in ...

How Can Electrolytic Capacitors work for AC Motor Starting?

Electrolytic capacitors are essentially polar components, and are rated for DV voltages. They cannot sustain reversal of polarity, and a voltage of reverse polarity can damage the capacitor (they are practically a short-circuit in reverse direction), though a very low voltage of say, below 1 V AC for short time may not affect it significantly.

Why capacitors do not work when they are connected backwards?

voltage

In reverse biased condition, the diode does not allow electric current through it. So the input current directly flows towards the output. When the negative half cycle begins, the diode is in the non - conducting state and the charge stored in the capacitor is discharged (released).

How can the capacitor be connected in reverse polarity?

However, it is still possible to put a AC signal thru a polarized capacitor. This is done by adding a DC bias of at least half the AC peak-peak voltage. The entire signal is then still positive, but AC-wise the capacitor acts on it normally.

The Fundamentals of Capacitors in AC Circuits

An AC ammeter connected in the circuit would indicate a current flowing through the capacitor, but the capacitor has an insulating dielectric between the two plates, so it is a displacement current that the ammeter records. The value of this current is affected by the applied voltage, the supply frequency, and the capacity of the capacitor.
