The Building Blocks of Modern Technology: Basic Electronic Components and Their Functions
An inductor is typically a coil of insulated wire wrapped around a core (like iron or air). When current passes through the coil, a magnetic field expands. If the current changes, the changing magnetic field induces a voltage that opposes the change in current (Lenz's Law).
These components can amplify signals or switch electrical paths and are primarily made from semiconductor materials. basic electronics components and their functions pdf
: Store energy in a magnetic field when current passes through them; they are frequently used to filter out unwanted high frequencies. : Allow current to flow in only one direction. Light Emitting Diodes (LEDs)
Inductors are passive components that store magnetic energy. They consist of a coil of wire wrapped around a core material. Inductors are measured in henries (H) and are used to: The Building Blocks of Modern Technology: Basic Electronic
These components use electrical energy to create mechanical movement or use physical action to connect/disconnect circuits.

Function revealed: allows current to flow in only one direction (rectification).
These do not need external power. They consume, store, or regulate energy but cannot amplify signals (e.g., resistors, capacitors, inductors). Sierra Circuits 1. Resistors: The Traffic Controllers
