Question

Is a diode active or passive?

Answer 1

1. Active components are circuit elements that depend on an outside power source to regulate or alter electrical impulses. Transistors and silicon-controlled rectifiers (SCRs), active components, use electricity to regulate electricity.
2. Transformers, resistors, and diodes are examples of passive components that don't require an external power source to operate. To control the electrical signal, these components make use of some other characteristics. They therefore just need the current flowing via the connected circuit. Without adding more electricity to the system, resistors block the flow of electrons.
3. A diode is an active element since it will have internal energy at the time of production. Active components, which include all kinds of sources, diodes, transistors, and members of the SCR family, among others, are those that possess internal energy at the time of manufacture.

Therefore a diode is an Active component.
