Difference Between Active and Passive Components

The active and passive components are differentiated on various factors like nature of the source, its functions, power gain, controlling the flow of current. Various examples of the component, nature of the energy, requirement of the external resistance. The Difference Between Active and Passive Components is given below in the tabulated form.

BASISACTIVE COMPONENTSPASSIVE COMPONENT
Nature of sourceActive components deliver power or energy to the circuit.Passive elements utilizes power or energy in the circuit.
Examples Diodes, Transistors, SCR, Integrated circuits etc.Resistor, Capacitor, Inductor etc.
Function of the componentDevices which produce energy in the form of voltage or current.Devices which stores energy in the form of voltage or current.
Power GainThey are capable of providing power gain.They are incapable of providing power gain.
Flow of currentActive components can control the flow of current.Passive components cannot control the flow of the current.
Requirement of external sourceThey require an external source for the operations.They do not require any external source for the operations.
Nature of energyActive components are energy donor.Passive components are energy acceptor.

In this article difference between Active and Passive components are explained considering various points. Active components are the elements or devices which are capable of providing or delivers energy to the circuit. Passive components are the devices which do not require any external source for the operation and are capable of storing energy in the form of voltage or current in the circuit.

The Difference Between Active and Passive Components are as follows:-

  • Active components are those who delivers or produce energy or power in the form of a voltage or current. Passive components are those who utilises or store 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 are capable of providing the power gain, whereas the passive components are not capable of providing the power gain.
  • Active components can control the flow of current, but the passive components cannot control the flow of the current.
  • Active components are energy donor, whereas the passive components are energy acceptor.
  • The active component requires an external source for the operation, whereas the passive components do not require any external source for the operations.
