In electronics, there are two main types of components: active and passive. Active components are electronic components that require an external power source to function, and they have one or more active electronic components, such as transistors or integrated circuits. Passive components, on the other hand, do not require an external power source to function, and they do not have any active electronic components.
Active components are typically used to amplify, switch, or otherwise control the flow of electricity in a circuit. Examples of active components include transistors, amplifiers, and oscillators. These components are crucial for many electronic circuits and systems, as they allow for complex operations and control of the circuit.
Passive components, on the other hand, are typically used to provide electrical resistance, capacitance, or inductance in a circuit. Examples of passive components include resistors, capacitors, and inductors. These components do not require an external power source to function, and they do not have any active electronic components. Passive components are simpler and less expensive than active components, and they are typically used in circuits that do not require complex operations or control.
In summary, active components are electronic components that require an external power source and have active electronic components, while passive components do not require an external power source and do not have any active electronic components. Both types of components are essential for many electronic circuits and systems, and they play different roles in the functioning of the circuit
