Working Principle

The working principle of an aluminum electrolytic capacitor is based on the electrochemical reaction between aluminum metal and an electrolyte. The electrolyte is composed of an aqueous solution of boric acid and a small amount of ammonium chloride. This solution is housed between two aluminum foils. One of these foils is an anode foil while the other is a cathode foil.

The anode foil is made of a high-surface area aluminum material, whereas the cathode foil is made of a low-surface area aluminum material. The electrolyte and the two aluminum foils form a kind of a sandwich between two porous layers.

When the capacitor is connected to a voltage source, electrons flow from the anode to the cathode. This causes a reaction between the electrolyte and the aluminum foils. The electric current generated from this reaction makes the aluminum foils an anode and a cathode, thus creating an electric field around it. This electric field is responsible for storing charge in the capacitor.

The charge stored in the aluminum electrolytic capacitor is proportional to the voltage applied. This means that as the voltage is increased, so will the capacitance increase. This is why an aluminum electrolytic capacitor is ideal for applications like power supplies, computer circuits, audio amplifiers, and medical instruments.
