Active
The elements which are capable of delivering energy are called "Active elements".Examples of active devices are Transistors, Triacs, Varistors, Vacuum Tubes, relays, solenoids and piezo electric devices.

Passive
The elements which will receive the energy and dissipate or store it are called "Passive elements".The three linear passive elements are the Resistor, the Capacitor and the Inductor. Examples of non-linear passive devices would be diodes, switches and spark gaps.
