Differences between active and passive electrical components

Active Components vs Passive Components

Active elements in the circuit are components that provide power or energy to the circuit by extracting the power from an external source.
 
Passive elements in a circuit are components that cannot produce energy in the circuit in which they are operated. However, they can store or consume the power present in the circuit.
 
Active component is equipment that can amplify the output signal of an electronic circuit in the amount more than in the input signal.
 
Passive components are tools that control or alter the output of an electronic circuit without playing an active function in their performance.

One factor that distinguishes electrical components is their Active and Passive. In this article, we will examine the Active and Passive electrical components and the application of each and the Difference Between Active and Passive Components Stay with us.

 

 
Active components include diodes, transistors, and inactive components include resistors, capacitors, and inductors.
 

Diode :

A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from cathode to plate.

 

 

Resistor :

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat, may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity.
Changing the electrical current applied to the material steers the flow of the current in different directions. So, at the flip of a switch, the new material goes from letting the electrons in an electrical current flow to blocking them, or forcing them to move in specific directions at particular times: From acting like a transistor to acting like a resistor, or even a diode or a rectifier. Read more
