The type of capacitor used only for DC (Direct Current) applications is the Electrolytic Capacitor.
Electrolytic capacitors are polarized, meaning they have a positive and negative lead, and they are typically used in DC circuits, especially for filtering and smoothing purposes in power supplies. They have a much higher capacitance compared to other types of capacitors, which makes them suitable for DC voltage applications. However, they should not be used in AC circuits because their polarity could be damaged, leading to failure.
In AC circuits, other types of capacitors, such as ceramic, polyester, or film capacitors, are generally used, as they can handle both AC and DC signals.
