Why is the capacitor a passive device

Difference between active and passive components

The active and passive components are differentiated according to various factors such as type of source, functions, increase in performance, control of the current flow. Different examples of the component, type of energy, requirement of external resistance. The difference betweenactive and Passive components is given below in tabular form.

This article explains differences between active and passive components with a number of points in mind. Active components are the elements or devices that are capable of supplying or supplying energy to the circuit. Passive components are the devices that do not require an external source for operation and are able to store energy in the form of voltage or current.

The difference between active and passive components is as follows:

  • Active components are those that deliver or generate energy or power in the form of a voltage or a current. Passive components are the ones that uses or stores energy in the form of voltage or current.
  • Examples of the active components are diodes, transistors, SCR, integrated circuits, etc. Similarly, examples of the passive components are resistor, capacitor, and inductor.
  • Active components can provide that Power gainwhile the passive components are unable to provide the power amplification.
  • Active components can control this Current flow, but the passive components cannot control the flow of current.
  • Active components are energy donors, while the passive components are energy acceptors.
  • The active component requires an external source for the operation, while the passive components do not require an external source for the operations.
