Is all polar components active components?

Not all polar components are active components. In electronics, active components are those that can introduce power into a circuit, such as transistors and operational amplifiers, while passive components (like resistors and capacitors) do not provide power and only store or dissipate energy. Polar components, such as certain types of capacitors (like electrolytic capacitors), have polarity but can be either active or passive depending on their function in a circuit. Therefore, the classification of a component as active or passive depends on its ability to control current flow and provide energy, not solely on its polarity.
