Some common insulating materials are mica, ceramic, paper, and Teflon™ …
Is capacitor an active or passive device
A capacitor is considered a passive device in electronics. Passive devices are those that do not require an external power source to function but rather respond to applied voltages or currents. In the case of a capacitor, it stores electrical energy in an electric field between its plates when a voltage is applied across it.

What is capacitive loading? (Intuitive understanding)
A useful capacitive load is, for example, the capacitor in an RC integrating circuit. In this case, its slow charging is something we want, because it allows us to get an idea of the time through the voltage (hence the resistor in series to the capacitor). In this way, we can make timers (555), ramp generators and more. In other cases (e.g., dynamic RAM, …
